Hi fellas,
I'm about to do a 73-87 (1991 Suburban junkyard front end; 88-91 Suburban = 73-87 pickup front suspension) front crossmember swap on my 62 GMC big block V6.
The 60-62 ball bearing wheel bearings may as well be obsolete as the only available replacements are inferior quality and will burn up frequently, ball joints are OBSCENELY EXPENSIVE & getting scarce (& mine are worn out), and I got a nice set of 5 lug American Racing Torque Thrust D wheels and had my rear axles welded up, machined smooth, and re-drilled for 5 lug. So a 5 lug front with readily available parts, disc brakes, and a sway bar is a welcome upgrade without a doubt.
Here is some great info for this conversion:

and specific swap photos/info for a 60-62:

I also wanted to point out for those looking for a 6 lug rear disc setup, modern Dana 44's on Isuzu Rodeo's (also rebadged as Honda Passport?) from 1993 or 1994+ or maybe it was 1998, are 6 lug on 5.5" and these can be swapped onto our rear ends with a little modifying of axle register or rotor hole, and bolt pattern adjustment to backing plates, and actually the whole rear can be swapped and is a slight bit narrower than the GM corporate rear ends from later models, so this is a welcome thing for the early model 60-66 trucks that use a narrower width rear. IF someone has a rear end needing replaced. Of course suspension mounting points would need to be fabbed/modded. Then you can do the front end swap and use 6 lug aftermarket rotors if needed.
I also would like to point you towards a GMC truck Dana 44 rear end disc brake conversion thread that I started, and compiled a ton of info on, for late model Dana 44 rear brake setups with integral rotor hat drum parking brakes, vs the now getting scarce old Cadillac Eldorado/Seville Riviera Toronado & WS6 Trans Am rear disc calipers with the mechanical worm gear parking brake actuator assembly built into the hydraulic piston. These have been very popular for swaps, but are getting scarce and with expensive core charges, but using some big ford 9" application brackets for these calipers, can be bolted directly to the Dana 44 GMC rears.
