Help with the K member!
The two K frames are a direct interchange
The one you are putting IN is?? a V8?? K?? It should be, that is should NOT be a /6 K frame or you have gained nothing
All front end parts off either car---if they are both disk brakes, will interchange
If one is drum, and you are converting to disc, you need the "disc" parts from one car:
the upper A arms
The spindles and upper and lower ball joints, and of course calipers, etc
As ^^ above, you need to tear it all apart, anyway, because you need to replace all bushings and moveable / wear parts in the front end, unless the "donor" is fairly newly built.
