Yes I would like to know this also. Seems with the scarcity of 71 -72 rear diffs out there, a guy could swap out to a later model rear differential. Would it be hard to line up new coil mounts and trailing arm connections on a later model diff?
Seems like some one would have already done something like this, ie a 73-87 C10 rear in a early 60's C10 (Given the fact that the front brakes and suspension are swapable, I would think the 73-87 rear diffs would have the same width/tracking as earlier rears)
Am I way off?

measure both axles see if they are even close.Is your truck leaf springs or truck arms?

I have a rear end out of a '76 in my '72... But I'm running a heidts 4 link.

The Yukon axle is wider than the stocker if you plan on running staggard wheels that's not a problem you can just correct this with a custom offset.

You will need to cut all the old mounts off and just weld new ones on.

I have been wondering the same thing. I have a 2006 gmc pickup with a 4.8 vortec and entire drive train. the doner 06 is actually a complete pickup so I can use anything from the pickup I want.
what all will be easily transferable to my 68 c-10 short wide?

of course I will use the motor and trans. but have wondered if I will be able to use the rear end and all of its component or not? anyone know the width difference in the newer rear end?

can I adapt the brake system from the 06 to my 68?

i imagine the braking system can be made to fit. i would have to replace the lines and prop valve and master cyl to accomodate the rear disk.
but any idea how much wider the rear end than my 67? I had shoulder surgery so crawling under my truck right now with a measure tape is out of the question for a couple more weeks.
Im running 15x10 in the rears with my og 67 rear end. im thinking an inch or two wouldnt really hurt me much. i put disk in the front so that popped out my front tires about 1.75"
