So my question is will these C20 LCAs fit on my C10.
Will a C10 lower ball joint fit the C20 arm?
Whats with the bushings. How do you service (replace) them?
Are the c20 uppers any different than the c10? I read somewhere that the shafts were thicker giving added positive camber. ?
This is on a squarebody 81+
Thanks

C10 lower BJ's are smaller OD vs C20 so they won't fit into the C20 lowers.
The different bushings are the same used pre-73 for all GM trucks. They're the standard metal sleeve w/a rubber lining. Local auto parts should still carry them (they screw onto the arm/shaft combo).
The C20/30 upper shafts are thicker which would yield more positive camber vs the C10's w/the same qty of shims. But... the C10 upper shaft studs are 1/2"; the C20/30's are 9/16" so using the C20 shafts would require the larger retaining studs (& the work to make it happen).
