Yeah these are Gemini ones but I had to machine down the shell so that it would fit. Just couldn't press it in otherwise. Only had to take off about 0.5mm I think. I suppose they figure the Gemini arm is going to have some give in the holes being thinner steel. Also Gemini arm holes would've been spread out once already from the original bushes installation so I suppose they're compensating for that too. The standard bushes on Gemini and JR arms appear to be the same.
Mine aren't Super Pro ones though so those could be fine.
