I just put mine in, and they fit good. Did you take all of the old bushings out? I took a few pics, i'll try to post them as soon as the battery recharges!
When I got the arms they didn't have any bushings in them - just bare aluminum arms. The problem is that the beetle bushings are smaller in diameter than the 944 turbo arms bores.
Ahh, I see, looks like there should be a metal sleeve that should be there that yours is missing. if you want give me your email, and I'll get you some pics of what it should look like. cudabnu (at) yahoo (dot) com
