Introduction


The Mustang pictured below (bottom) was first purchased by my father-in-law, Buddy, in 1986, in Connecticut. Shortly after, he purchased a second six-cylinder convertible and sold the pictured one to my wife's cousin, Ronnie. Dad died in 1994. When Ronnie decided to sell the car to finance an in-ground swimming pool in 2006, my wife Sharon and I decided to buy it, and brought it home to Tennessee.
The car had undergone a cosmetic restoration before Dad bought it, and apart from some minor detailing since then, was still in the same condition when we bought it.
In June 2010, I found out it was a Sprint 200, Package A, 3-speed manual transmission. And after reading an article in the archives of the Mustang Times by Jim Smart, went looking for the Broadcast (Build) Sheet. I found it wrapped around the wiring harness behind the speedometer. After a brief search to find out what all the codes meant, I realized that surprisingly little is known or published about these documents. So I decided I'd try to attempt to decode it myself. This blog is a journal of that research.
All discussions below currently pertain to only 1966 Mustangs.

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.
