got an 86 camaro with a drum rear and a doner car 85 trans am with a 9bolt disc. the lines and all misc. parts on the bird were decayed and half of them broke off when i was taking the rear out. question is, what do i need to change when i pop the rear into the camaro? im missing everything that came with the 9bolt besides the calipers and bolts. missing the lever and misc. nuts and bolts and lines. i have the mastercyl out, should i just swap it right into the camaro? i know i need to change the proportion valve but was wondering if just putting the whole thing in would be easier.i know this question has been asked a million times already because i remember reading about it but help me out here im stuck...
