nice truck,
before you ditch the cab take a look at a few other builds and see what can be saved. If you really want to make it a 67 you can buy side marker light filler pieces and weld them in before you finish your body work. Don't get rid of any OEM sheetmetal if you can help it.
I agree with the trim though, I like that it's complete.
Take a look at this thread to see what a nice "patina" a 67 can make look nice.
