What Year Is My Truck?

[SierraMtns]

Ok so I am not sure where to begin. Here it goes. The truck is "registered" as a 1967. However after starting to work on it I started to notice little things that got me thinkin, is this really a 67?

Last night I went to our local 67-72 parts guy and picked up some 67 door panels but they DON'T fit.

I need your guys help to figure out roughly what year cab and doors I have.

Here are the panels that don't fit. They have a ledge at the top that slide under and then bolt at the bottom.



Here are the doors on the truck.



Here are other pictures inside the cab. I thought I read somewhere that the ashtrays on the 67 are smaller?

Under the pedals.



Thanks for the help.
