I did that swap on my dads 71 3/4 ton 4x4
only i also swaped the front dana 44 for a dana 60. every thing bolted tight in
the sping perches were lined up perfect from the old stock rear end
all I had to do was shorten the drive line a littel and put littel wedges under to get the right angle for the rear drive line
