Does anyone know if the upper control arm brackets that are bolted to the frame need to be changed if doing a C-10 to C-20 front suspension swap. I know the upper control arm studs are a larger diameter for the C-20, but I am not sure if the C-10 bracket can be drilled or if it needs to be changed.
Wanted upper control arm brackets '64 C-20 Does anyone have or know of anyone that has the right and left upper control arm brackets that will work on my '64 C-20?
