"7MM vs. "7MA" ???
Danny and Neil:
First to answer Danny's question..Stock steel is what I'm looking for..See attached (hopefully) photos. Originally, I was mistaking the "7MM" under the FoMoCo stamp as referencing the rim size of "7" because the second M didn't match up to any of the date decoders I was using...It made sense that the first M would be "Motor Wheel Corp.", but up until this morning, my understanding was that the third digit for wheels could only be A thru E according to the decoders I'd previously seen. But, this morning, I came across a FoMoCo Parts decoder (
http://www.karmustang.com/date_codes.php) that shows "Date Codes for 1968 Model Year" parts production date as "M = December 1967," similar to how body date codes are designated on our door identaplates. So my puzzle may have just become more confusing...So far, I've been told that GT/CSs were only sold with 14 x 6 wheels...these wheels measure 15 3/8" outside diameter by 7" outside width (roughly 14 x 6.5 at the inner tire beads), and had rotted 205/75 x 14 tires on them when I bought the car, with the stock full covers that you see in the photo attached. So, the question is, did someone swap out the original wheels for these, or is it possible that since my car was built in Feb '68, it received 14 x 7 wheels that were produced in Dec '67? Auto-Forensics-101! Ultimately, Neil, it sounds like the rim you have may work as a match to my three good ones. If you don't mind comparing the photos and taking some measurements, I'd be greatly appreciative. Sorry for the long drone, and thanks always for the generosity of your knowledge. Josh
