I have nice American Racing 15x8 5 lug wheels and a 1991 (73-91 suburban/73-87 pickup all same front x-members) 2wd disc brake coil spring front crossmember to swap on primarily to have stock off the shelf parts with a long model run for best availability, $40-90 in ball joints vs the 62 GMC $450 in ball joints, worth it alone - entire premium front end rebuild on the 73-91 front end will be less than the 62 ball joints! Plus I get to ditch the 60-62 ball bearing front wheel bearing setup, as if they need replaced, new replacements of any reputable quality are becoming more and more difficult to find, so switching to the 63+ tapered bearings brings much better quality into the picture, as well as more reduced cost...

Here's a tutorial on bolting up a 73-87/91 (thru 87 pickup, same as thru 91 Suburban) front crossmember onto a 60-62. The 63-66 or 63-69 (when was the first year for front discs?) is slightly easier, more holes line up on the existing frame.
Basically you end up with 2 holes on each side that line up, and you have to drill 3 more holes and elongate 1? and then relocate the shock upper mounting brackets. Also, if not using the 60-62 idler arm, you have to drill mounting holes for the 73-87/91 idler arm.

I wish it were as easy as a 4x4 where you have a 2 pc splined slip fit driveshaft and a transfer case/driveshaft output flange, where you can just bolt up an e-brake rotor and mount a mechanical caliper bracket kit... Then run front calipers on the rear and not worry about e-brake at the wheels.
