[1964C10]

John, looking at this:

Option 2: (done by dream68)
The '88 spindle, rotor, calipers, and ball joints were used in the swap, but you need a 3/4 ton '68(For other year options see above in section 1963-1966/6 lug/V8) a-arm instead of the 1/2 ton one. The bottom '88 balljoint fits into the '68 a-arm, and the top '88 ball joint fits on the '68 a-arm. The top '88 ball joint you half to grind the rivets off of the 88 a-arm and then bolt it to the '68 a-arm. For steering linkage keep the 1968 1/2 ton intermediate shaft, 1988 1/2 ton tie rods, with the inner tie rod end changed to part#: MOOG ES2020. (done by dream68 on a '68 but should work on these years as well).

I think that answers your question(?)
