Will check to see if the production year MPC carries the same part numbers and get back.
Ok checked a April 68 version of this section in the MPC and came up with the following. Seems as expected that Ford changed recommended parts between when they were producing some of these cars and almost 10 years later. Also reformatted to fit the one that John already posted for easier comparison
Year------------------Trans------ Engine----------- Part Number67- through 4/68------Manual------ 289 & 302-------- C5ZZ-9725-A
67- through 4/68------Manual------ 390-------------- C5ZZ-9725-A
67- through 4/68------C4----------- 289 & 302-------- C6ZZ-9725-A
67- through 4/68------C6----------- 390-------------- C7ZZ-9725-A
68- through 4/68------All----------- 428CJ------------ C8ZZ-9725-A (427 4V is also shown under this part number)
While I'm posting here are the other 67-8 applications listed
Year------------------Trans------ Engine----------- Part Number67- through 4/68------C4----------- 200-------------- C7ZZ-9725-B
67- through 4/68------C6----------- 200-------------- C7ZZ-9725-C
As always - what is in the MPC is what Ford carried in stock when the catalog was printed and is not always reflective of what was used on the assembly line to build or cars. These parts often vary in looks, details or design. Standard warning for readers
