It will tell me that a 4x4 1/2 ton frame is different than a 2x4 3/4 ton frame. This is what I found in my measurements.
These measurements were taken from top to bottom of frame flanges. And both frames were 1/4" thick. The Bold is for the longhorn to try to see the difference in the post.
1972 Blazer 4x4 1/2 ton
1972 Chevy Longhorn 3/4 ton 2x4
6 1/8" tall behind front cab mount
7 5/8" tall behind front cab mount 1 1/2" difference
4 1/2" Tall above rear axle
5" Tall above rear axle 1" difference
Rear Spring Hangers On Frame
Front
Front
10"
5 1/2" 4 1/2" difference
Rear
Rear
7 1/4"
7 1/4" Same
So what this shows me is that the frames are different from 1/2 ton to 3/4 ton. Now this could be different with the 2wd coil spring rear suspension trucks. But not with the leaf spring 3/4 ton trucks. Basically the 2wd 3/4 ton frame I have is the same as a 4wd frame almost. Since some holes are different up front I realize they are different. But that shows a comparrison on frame heighth.
And for the rear leaf spring hangers. I had it backwards. Everyone told me the rear hanger was longer on the 4wd's than the 2wd's. Well in reality it is the front hanger that is almost 4 1/2" longer than the 2wd one. That is a big difference. And the rear ones are the same.
