I used rockauto.com for all my rebuild parts, bought parts to rebuild upper control arms and after getting them off ended up just buying the brand new uppers from rock auto, they were $105 for the pair. Come pre-assembled with bushings, rod and ball joint. Probably take my old upper control arms one weekend and rebuild with the parts I have for a spare set. I used the Western Chassis 2.5/4 drop on mine, spindles, shackles and hangers. Although have yet to put the hangers on, I do plan on getting some 1 or 2" drop coils to to put in as well.
I bought all Movotech parts but they also offer AC Delco, MAS and Moog brands.
Here are my carts from the rebuild...
Also did new rotors, calipers, pads, lines....etc
Have since also pressure washed and painted the inner fenders black.
