What is the width of a rear end in a early 80's c20 2wd?

Any ideas where to look?

67" assuming you have the full floating 14 bolt in the rear.

For my 89' V10 blazer (4x4), my front WMS to WMS (wheel mounting surface) is 67-1/4"
My rear is 63-1/2" WMS to WMS plus drum thickness. So approx. 64"
These are 1/2 ton axles.

A 1990 2wd 2500 truck with 14SF axle is 64-7/8". However the spring perches/shock mounts are different. Trucks changed body to IFS in 1988. There is also a wider one that's around 67 or 68" (two of the 14SF out there).
