obs disc on 63-66 C10 upper arms?

[Kriegs]

Hi, while researching on disc swaps for my 66 c10,i found the faq,among other threads on doing the disc swap. http://67-72chevytrucks.com/vboard/s...d.php?t=367260 i follow most of it but......can i use 3/4-1ton(c20/30) upper arms 73-87(truck)/91(subs) in place of the older 64-66 c10 arms.I would like to upgrade, to the rubber bushings on the shaft? as well as keep the same year control arms instead of having 3 different years of arms,brakes,and steering components?(66 upper,73+ lower,88+ spindle/brake/tierods) as well as getting the arms from the same donor while there.

I used a 1990 chevy front end/parts that had 5 lug 1.25" thick rotors and went to AutoZone and bought new factory 6 lug 1.25" thick rotors and bolted them on. (thanks firstgen)
Basically these are the parts I used:

1968+(73-87 upper/lower?) C20 lower control arms
1988+ 3/4 ton Light Duty 2X4 must have (1.25" rotors) spindles
1988+ 1.25" thick 6 lug rotors
1988+ calipers off same truck
1988+ upper and lower ball joints
1988+ outer tie rods
inner tie rods MOOG part #ES2020RL
1988+ style tie rod coupler"

Spindles from any '88-'98 1/2 ton or light 3/4 ton 2wd pickup or suburban. Rotors from a 7200# GVW 3/4ton from '88-'98 (for some reason there is one part # for '88 & '89 and another for '90-'94. There are only minor differences between the two) I bought the one for the '90-'94 which is Raybestos #56915RGS. The ball joints you need to use are the ones for the '88-'98 spindles. The uppers will fit '63-'87 1/2 ton upper a-arms. The lowers will fit '69-'87 3/4 ton lower a-arms. The '69-'72 are prefered because of the shorter bump stop bracket. The newer ones could be easily modified. For steering you will need to use the '88-'98 outter tierod ends and the adjuster sleeves with ES2020L (ES2020RL?) inner tierod ends to mate up with the drag link. The calipers to use are the '88-'98 ones. Other than some minor things and replacement parts like bearings and seals, etc, I think that's about it."
