i can tell you the axle will bolt in basically .

i did a axle swap from a 1969 c60 napco 4x4 truck to a 82 c60 2wd truck . the only real difference was spring width in the rear . but this wasnt a problem since i used all the axle u-bolt plate mounting from the 1969 axles . just got the u-bolts made for the width of the new springs .

then shock mounts had to be welded on the axles in a different place still no problem .

last was the steering . i had to get a tapered reamer and open up the drag link hole from 1969 size to 1982 size .

she is driving down the road just fine now .

and the tires might be 19.5 since its a old u-haul and then had low load height trucks. 34"-35" is about the max height tire you will find in 19.5 rim size .
