I already have the 34 Chevy pickup doors and recently found a 35 Chevy pickup cab. Have not seen the cab in person, just a couple pics that didn't show the door opening clearly. What does the experts say? mike
@wingedexpress is correct. The only difference in the high cabs is the rounded lower windshield corners on the '35-'36.
The only high cabs to have the rounded lower windshield corners were early '36. I have one. The doors are interchangeable for '34-'36 high cabs. FWIW, My dad has '36 high cab doors on his 34/35 (no cowl tag to identify which year it is). The '34 doors had a lot more wood structure and the '36 doors had a lot more steel structure, but the shapes are the same. That should answer any question you have about compatibility. The 34/35 high cab truck bodies were nearly identical outside of a few minor details.
