I got a decent quadrajet from my brother in law as well as the axles. After I got the tires on the truck I took it for a little drive and well the carb is worn out just a little. I needed to get some new lug-nuts to install the new tires/wheels and I bought a carb rebuild it as well. Actually I bought both kits the store had cause I didn't know which one I needed. But after digging through this forum for a good bit I wanted to pass on this website that was mentioned on to anyone else that needs the same help I did.

Also, the kits from O'reilys are made by Walker Products, and here is another website that has, what I think, is some good information for rebuilding these old Quadrajets.
