A Meager Beginning

I made a few contacts over the little time I've been a Mustanger. I've emailed some of these individuals  and requested build sheet samples and decoding info. I've also searched online for samples embedded in forum posts. To-date I've managed to obtain (11) 1966 and (6) 1965 build sheets.  All of these samples have been from the  Metuchen assembly plant.
There were 607,568 Mustangs built in 1966, 559,451 Mustangs built in 1965, and 121,538 Mustangs built for 1964-1/2. And I've only managed to collect 17!!! More samples are going to be needed to explain some of the more difficult codes. But I am beginning to make some progress.

My Broadcast Sheet

My Broadcast (Build) Sheet 

I found my build sheet taped to the wiring harness behind the speedometer. They've also been known to be found under seats and carpeting. The tape was a kind of black cloth electrical tape, not too uncommon for the 1960's, but after 44 years was hard and difficult to remove. The tape obscured the lower left-hand corner of the build sheet. Careful soaking with acetone (applied with Q-tips) softened the tape and glue, allowing me to remove it and reveal the area below. While the acetone had no effect on the original heat-set print or paper, I'm not so sure about the type-written ink of the codes. I'm not sure if any codes existed here, and were removed with the tape and acetone, or if none were ever present.
