For the A/B-body 8.5" rears you have to get the adjustable upper control arms :idea:

You don't only need adjustable but you need 12 bolt swap arms (they corect the angles and have sphereacle joints). Umi or iceman racing both have them. I have the icemans serch 12 bolt g body on eBay to find them or Google umi for there's. You will also need a conversion u joint. I have the part number for the 8.2 10 bolt but not the 8.5. I took a tape mesure and mesured the factoy ujoint and the new yoke and googled "how to mesure u joints" and it gave me a great website that told me what part number I needed. As for other mods needed the spring perches are in a diffrent spot, I didn't move them and it worked out fine. The stock lower control arms will work. As for rims I had a set of factory iroc camaro rims that the offset was perfect.

I'm sure Ritter meant conversion adjustable, this topic has been brought up so many times all the regulars know it by now..

Yes, sir ... but a valueable point to somebody that doesn't know that. I did forget to mention that they must be conversion arms

for the u-joint head to Napa and they have a book with u-jonts, the book has the conversion u-joints listed and if you don't know what you need just look up which u-joint the rear end uses by looking up the car it came from and then your joint, with those two you pick the conversion joint that matches
