Re: c10/c20??

LWB C10 and most C20 trucks have the same wheelbase at 127". C20 Longhorns have a 133" wheelbase. How do you mean longer and where?

At the most basic level these are the four pickup frames.
C10 115"
C10 127"- 6.04" section height, 2.53" flange width, 0.156" thick, 2.98 section modulus

C20 127"- 6.11" section height, 2.46" flange width, 0.194" thick, 3.71 section modulus

C20/30 133" (Longhorn)- 7.20" section height, 2.77" flange width, 0.194" thick, 5.05 section modulus
