convert a 1971 c30 dually into a srw front

Please excuse my ignorance captain condescension. I did read all of it. Its a lot parts trading and info. I was looking to clarify. I can pull the hubs, with caliper and cage off and slide it right on his 71 c20? Install an axel nut and offset bud wheels?

No, your reading comprehension owns you
read it again, and it not a lot of parts trading, 3 per side SPINDLE, HUB/ROTOR assy, CALIPER

A a side note, for 72 and earlier, both 3/4 and 1 ton used a 1.25" thick rotor with 2 9/16" dia. caliper pistons. Starting in 73, the 1 tons could come ordered with the JB8 (or JD8) option - which got you a 1.50" thick rotor and 3 1/16" dia. piston calipers. On these larger JB8 1 ton brakes, the spindle was different only because these thicker rotors used the heavy duty "wedge" style calipers, rather than the "2 pin" style calipers found on the 3/4 and 1/2 ton vehicles. You could swap out the DRW ("dually") rotors on these and swap in a SRW JB8 (1.50" thick) rotor, and everything else was the same - the difference was solely in the depth of the DRW rotor. I only mention this because some people want the larger 70-80's JB8 brakes in a SRW package in their earlier 67-72 3/4 & 1 ton trucks, and also give more options if you're hunting down parts. The lower control arm and ball joint for the 3/4 and 1 tons are different from the 1/2 ton for these years (73-87).

Ill leave it to the experts above on the swap'ability of strictly 67-72 brake parts b/n C20 - C30.
