I am in the process of reassembling the automatic console shift on my 64 Galaxie XL. The parts I have were removed when I disassembled this for restoration but were not assembled per the exploded view from the manual. Specifically, I am trying to determine what part 7C451 is. It appears to be a shim, possibly up to 1/4" thick, that acts as a spacer between 78052 and 7C448 to create a gap for the gear indicator to pass under the transparent indicator lens 7A213. There are two plastic L-shaped shims that I removed from the assembly, shown in the photo, but these were mounted under the holes on the opposite side of 7C448 apparently serving no purpose. I believe this is incorrect. But they also don't appear the correct thickness or profile to create the lens gap. Any help in how this is supposed to be assembled is appreciated.
