The best thing to do is swap out the whole crossmember w/A-arms & spindles, or just the A-arms & spindles from a 73-87 Chevy C20. I'm doing this to my 66 C20 (A-arms & spindle). It's a toss up on what would be easier. If you swap the whole crossmember, you have to remove or support the engine. I think the crossmember to frame holes have to be enlarged.
Since I'm doing just the A-arms, I just have to enlarge four holes to 9/16" on each side on the crossmember for the lower A-arm. I have the '82 booster/master cyl & brake lines to install. Looks like they should install with no problems.
The GVWR on the '66 is 7900 w/drums & the '82 is 8600 w/disk (heavy duty JB7 or JL7). The truck should stop much better. If you want some pictures, PM me w/ your email.
