Trade a 73 C/20 454 for a 79 Jimmy 4x4?

[motornut]

check the top frame area around the rear wheel,
right behind body mount and before the shock mount
there is a small pocket there between the two, holds salt well
my 79 is a 203 transfer case full time 4X4,
i see manual hubs? not the "right"way to unlock it unless it has a kit
even then most need to run in the 4X4 to lube it,unless the filler tube is extended
had no probs pulling my small trailer(20') but wouldn't try more then moving my (30')
