I find tons of great knowledge on this board, and assume that Jim PA knows a lot of things about these trucks that I do not know. I do not own a C10 (1/2 ton) and probably never will, so I cannot go out to the garage and measure one. However, I do own some 72 Blazers and - am assuming - that the Blazer frame is the same size as the 1/2 ton frame. Maybe not the case?

If it is true that the Blazer frame is the same size as the C10 (1/2 ton), my tape measure just told me the following about frame height - (did not measure other aspects as it is cold out there today)

Height of Blazer frame at location of trans cross member is just about 6 inches.

Height of C20 (3/4 ton) frame at same location is about 8 inches.

If the assumption about Blazer/C10 sameness is any good, that would mean that a C20 frame is about 33% taller than the C10 frame at one critical point.
