Does anyone know what the spring perch width is in the rear of a 72 K5 vs. a 78 K5?
Thanks in advance.

The 1972 & older 4X4 spacing is 40" center to center.

Great, 2 different answers. When I measured, I thought it was 41 1/4" so the 41 1/2" sounds better than 40"

Where are you measuring?
My rear axle is a 14BFF from a '77 3/4 4X4. I had to move the perches from 42.5" to 40" to get under my '71 Burb. 1972 and older 4X4's measure 40" center to center of the perch......that is 100% correct.
1972 and older 2 wheel drives with leaf-springs have a 42.5" spacing.
Are you measuring a 2wd or 4wd?

the one ton axle I have was 40.5 " and I had to move each side one inch out for my 81' blazer to 42.5"

DOH!!
You're right! For some reason the newer 2WD dimension popped into my head. It might be because we swapped a 2WD 14BFS into a '72 4WD blazer recently. We had to narrow the perch spacingSorry about that ntroffroad.
