Jimmy , I'm going thru this same conversion with my '62 burb on a 78 4x4 3/4 ton chassis as well...mmm big brakes, and a rear end (14 bolt, 8 lug, full floater)thats strong as hell with cheap parts everywhere!

i sectioned the front half of the '78 frame 2.5" UP to get that "kick down under cab" porblem fixed.. also strentched the whell base 1/2" ,.. get front wheels a little more centered in fender (although i think i'd go the full inch next time)

sticking with ALL of the '78 drivetrain, i beleive this is the best way to really update... a little bit of work but not too bad...dealing with body mounts is a bigger job than this frame mod ...
and why use ANY of that old stuff anyway?

can post some pics of the progress tommorrow... gotta looong way to go! but it'll be well worth it!
