Well, he called me back and after talking with him he said to send all three back to him and he will shorten up the on that is too tall on the back side so it will line up. He did have a little trouble understanding what I mean't about the first one not lining up right on the last V-belt position so I am going to send him some pictures with some measurements to show him what I mean. It will most likely have to be re-made, and I can try to put in your request when he calls me back on it.

Geez, all he has to do is to place the pulleys side by side on a bench to see for himself. Not rocket science. He should have done this before sending them out.

Out of curiosity how much lighter is the under drive pulley compared to the original?

Btw did that rubber boot arrive?

Yea the boot arrived along with the gaskets.

As far as how much lighter, roughly 1/3 of the weight by guesstimate. The scale I have wont register the weight of them so I have to find something more sensitive...or an older mechanical scale.

It's a ****ing travesty. Can't even stand looking at it with that ridiculous ride height. at least until she goes over the pits.

While the project is temporarily on hold due to monetary constraints I've been maintaining an eye on on all things piazza stuff and have been acquiring bits and pieces along the way. Take this recent acquisition from eBay for example. Apart from the minor ink scuffs the booklet is brand new. It came from a Toyota service department in Adelaide.

Ditto. I have - or had - stuff like that for Belletts etc. I remember how happy I was when I found them but more so how surprised I was WHERE I found them.
Funny though - these days I don't seem to care. Maybe it's a case of "as long as I have the information (or know it - ie workshop manuals, sparts, etc).
Maybe I'll start framing them on the wall? (Some Bellett mates seem horrified when they see my dismantled Nostalgic Hero Bellett & Bellel extracts on the wall. Wait till they see what I'll do to my Bellett shells LOL!)


Beautiful looking Piazza though. It makes me realise I probably haven't seen a restored example. Resprayed perhaps, but usually still with the odd ding and still looking used.
Geez they look good (IMO).
Now to get a Japanese front spoiler kit for it. (I eventually agreed that they can look long in the nose, but the spoiler fixes that!) If it has one, ignore my last except for my taste ad endorsement. The rear boot handle & stubby holder certainly looks good (ha ha).

I'll probably be thinking like you down the track and think acquitions like this are ho-hum. But atm I consider it a find too good to pass up, especially when I consider it to be arguably rarer than the cars themselves. And to top it off no one else bid for it. A win in my books.

Hey guys, about time for an update eh! The popularity of Facebook has put a real dampener on activity on this forum. But I’m still here and there’s no better place to showcase your work-in-progress, mods, and rides etc than a forum like this. Don’t get me wrong, I like what Facebook brings to the table, and how it connects people from around the world really easily. But this forum will be still my go to spot for all things technical.

Now since my last post a couple of years ago I finally got my car back from my mechanic, had the car registered under historic rego, met some great like-minded friends, including Jeff Shein and his lovely wife who flew in from USA to see us in Sydney (nah only kidding).

Today I sold the custom intercooler that came with the car when I bought it. It makes way for another much larger intercooler core measuring 600x300x100mm (KLS Power Spirit 5002, universal fit) that I just picked up. This monster cooler was originally test-fitted on a VL turbo pumping out over 800hp, but the owner went a different direction with another engine combo and the cooler never went in. And it only cost me AU$100. Can’t want to put this sucker in once I relocate the battery to the boot.

Meanwhile I’ve had a chance to clean up the interior, exterior, and perform orange peel paint rectification work with my orbital polisher. Many hours spent on the paint let me assure you. There’s still some more work to do there, and I’ll end up having the front and rear bar resprayed hopefully sooner than later.

On the suspension side of things the nolathane bush conversion seems to be working well. Turn in and steering response seems sharper and direct. Anyway here are some pics of some red stuff. For anyone still interested I posted a full write-up in the Suspension section of the forum.

The headliner and surrounding trims will be given the same dark grey velour treatment. I expect to pick them up off the auto trimmer this week. More pics to follow when I reinstall it. Can’t wait. :bounce:

Moving onto LEDs now, and I’m navigating my way through replacing the standard incandescent interior lighting and rear number plate lights to LED. So far the number plate T10 LEDs that I replaced kept blowing my 15A fuse in about 3seconds flat. Has me stumped why, but I’ll try another set from another manufacturer to see if that fixes the problem. But the interior map light LED is a great and welcome change from the standard weak amber colour to the bright white light. These pics were taken in the daytime (in my garage):

More before and after pics of the LED conversion. This time it’s the interior 31mm festoon bulbs, which covers the door cards, centre dome light, and boot.

LED- the only downside here is that the LED doesn’t dim down anymore.

Installed the new headliner today, along with the same velour-covered trims for that premium look and feel. Headliner and trims were done by pro motor trimmer in my local area. I contemplated doing the work myself, but I’m glad I didn’t. Next job is redoing the sun visors, but in this case I’m pretty keen on chasing down better-designed versions than the originals that are way too thick and bulky. I hope to find a suitable replacement from the wrecker soon.

Just installed the HBL ‘88+ rear tail lights on the weekend after the wiring was re jigged to suit the existing wiring harness/connector. My electrician did a top notch job soldering on the delicate flexi-ribbon tapes and reconfiguring the wires out from the new clusters. Hot glue was then poured over soldering area to strengthen and protect the wiring.

In short, the swap-over wasn’t a plug-and-play setup. Thanks also to Thomas who gave me the heads up on the resistor/capacitors possibly overheating and causing a fire, I had that part disabled. The resistors and capacitors are used to send the appropriate warning signal back to the dashboard for any broken globes. On the original lights there were resistors and capacitors on both sides. On the later HBL versions there was a much larger resistor and heaps of resistors on the left-side tail light cluster only. This means the right-side cluster is somehow bridged/connected to the left side on the later +’88 models for proper communication back to the dash. I couldn’t risk there being a potential overheating/fire issue so I had that function disabled. No big deal in my opinion. Just maintain a visual check every now and then.

Next on the ‘to do’ list is fix the saggy sorry-looking mesh storage compartments behind the front seats. It’s obvious the offending elastic cords are perished and need to be replaced.

Easier said than done because the rear cover panels have to to be removed in order access the fixings to the mesh storage compartment assembly. Apart from unscrewing the rear covers you’ll also need to remove the lumbar adjustment dials and lever, all of which secured with circlips along the shaft of the dials and lever. So don’t bother trying to remove what appears to be caps at the top the dials. They aren’t real caps!

After removing the covers from the front seats you’ll find that the mesh compartment assemblies are secured by a number of small spring steel one-way clips that are designed to secure properly only once. Removing the clips pretty much buggers up the little soft plastic fingers that the clips grip onto. But that’s ok because there’s a better solution which I’ll explain later. The original spring steel clips won’t be needed anymore.

The perished elastic cord was replaced with new 4mm grey cord sourced online from Etsy. I have plenty left over so if someone is interested they can let me know and I’ll post it. But if you prefer to buy it yourself it costs about $6 to ship it from China anyway. (https://etsy.me/2QM7KVe select colour number 3 if you’re after the original look).

I went ahead and cleaned the covers, and washed the mesh in the washing machine. The covers looked way more dirty and scuffed after having a closer look at them on the bench.

The amount of new elastic cord that I used per side wasn’t much at all.

The little plastic fingers that poke through the back of the covers were trimmed down about 4mm with a Stanley knife, or enough so that they sit flush with the inner surface (back edge) of the cover. I then used little 4G x 6mm screws and small washers to secure the assembly down. Take extra care and do not over tighten, as the plastic is soft.

The end result looks perfect. No more saggy storage compartment. The grey colour of new cord was also spot on in keeping with the original look I was after.
