Not throwing a monkey wrench in on purpose
but the 60-68 MPC is interesting to say the least on this "12216 - wire assy. - distributor primary terminal"
The 67 MPC calls for:
C1VF-12216-A for distributors stamped with C5GF-12127-C
C2OZ-12216-A for distributors stamped with C4GF-12127-B
There is no reference to anything different about a T/E equipped C or A code.
Edit: I looked at my known original C code T/E distributor C7AF-12127-AH date code 6L7 and the body has a C7OF-12131-A stamp, which concurs with Mannel's book on page 7-23. Based on that I think that the 1967 MPC distributor mark references are hog wash.
The 68 MPC is different. Gone is the reference to two different distributor core stampings, but now a 289 HiPo reference appears:
C1VF-12216-A for 67 C code, automatic, except T/E. There is nothing for a C code manual, C code auto T/E, or any A codes. I guess quality was not job one. Looking at this again, the (2/B, C4) might only apply to the "X" car and not the "F". I don't know then if the "exc. T/E" applies to just the "X" or everything preceding. I suppose this is when the parts guy says "let me go grab one off the shelf and we can take a look at it"
C7AZ-12216-B for 67 289 HiPo
