I know a few have built their own A-arms, and am sure I have seen the pictures of them, but have been unable to find them recently. Does anyone have dimensions of the front A-arm points and ball joint location, especially in CAD, that they could share? I have the bushings pressed out of mine and will likely measure them anyway, but an extra reference is always nice to double check the numbers! For those that fabricated their own arms, if you have dimensions of your ball joint cup, those would be welcome as well. The last set of A-arms I built were non-sprung, so I got away with a really thin cup (~.180 thickness) around the ball joint on a 3900lb track car. I always planned on going back and reinforcing them, but haven't yet.
