Can you guys help me confirm my hypothesis on 67-70 trunk latch striker variations? I've come across three different versions, you can see in the pictures. They all have "M-S" stamped on the backside that is hidden when installed.
1967 Mustang - Pic 1 right, with two "windows" for the latch to catch (I assume so the striker could be installed either way)
1967 Shelby - not pictured. Not 100% sure what the difference is, but at
http://www.thecoralsnake.com/NOS he mentions seeing some early strikers with rounded corners to facilitate fitment (to the fiberglass decklids) Interchanges with 67 Mustang version.
1968 Mustang/Shelby - Pic 1 center, with extra wide mounting surfaces. Also has just one "window", possibly to save money on extra stamping costs.
1969-70 Mustang/Shelby - Pic 1 left, back to normal size mounting surfaces, but with one "window".
From my bookwork, I've found the following:
Ford MPC Service Part #: C7ZZ-6543252-A
Ford Master Cross Ref Engineering #'s:
C7ZB-6543252-A (April 1966)
C8ZB-6543252-A (October 1969)
Branda's 67 Shelby Assembly Manual on pg 30 shows: S7MS-6543252-A
Ford O.S.I. from January 1970 shows: S7MS-6543252-A MW (mix with) C7ZZ-6543252-A
The illustrations in the 1967-1970 Body Assembly Manuals seem to confirm my thinking, but I'm just curious how accurate this is in the real world. I find it mildly unusual that Ford would have the same engineering number across two versions (the 67 and 68 body assembly books both show C7ZB-6543252-A) but not unheard of. So, any thoughts?
