1967 Only or 60-66 Carry Over?

[BMERDOC]

As I'm planning the Ultimate Build of my 67 several questions have come up. I am planning a half custom/half resto of the truck and I want the 67 only stuff to be correct. I could research all this and maybe a thread is buried out there somewhere but I think a thorough thread is well deserved. So tell me...What is 67 only and what was a carry over? Was the visor clips 67 only? I think I have established that the window vent wing handles were a carry over from 60-66. How about the inner door handles? Were they 67 only? Was the e-brake for 67-68 from the 60-66s? What dictated wether or not the e-brake got a cover? Or maybe the POs just left them off after doing some work and they all got them? How about the 67 only ignition switch escution? Was that 67 only? I almost got lost in diagnosis until I found out that the front running lights on a 67 extinguish when the knob is pulled completely out and the headlights come on. What about this stuff? Is there anything I havent covered? Oh yeah, 67...no side markers, Rookie info.
