He created a 3/4 ton short bed because all of the short beds were light duty. What I have found wrong is no wood grain to match glove box on instrument cluster, missing brake pedal trim wrong steering wheel , They did not have power windows from the factory either . With out checking up close to see what was done is correct I would price that truck in the 12k range
I have had 14 67-72 chevys and know every inch of them
