First off . I have a 1990 c1500 with the 700r4 transmission . The 3,4 clutches are toast so I'm going to do a rebuild . And I have been looking just about everywhere for rebuild kits from master kits to super master kits and the monster in a box kit but none are complete kits . I want to bullit proof my transmission for durability . The 5.7 FBI in my truck us pretty much stock. Will later replace the old 350 with a crate 383. At around 450 hp . Where can I find a complete master rebuild kit for the 700r4 transmission?
