That would be the easiest.
You can reuse the original upper a-arms,... but you would have to swap in 73-87 1/2-ton balljoints.
So use the '86 a-arms.
(they also have rubber bushings instead of steel cross-shaft bushings)
Lowers definitely have to be swapped.
C20 lowers have a bigger balljoint hole in them,... than the C10 version.
Also use
all the steering linkage from the '86.
