Just over 23 years ago I purchased my current '66 Fastback. While putting around with it the first week I owned it, I discovered a copy of the build sheet (or broadcast sheet, if you prefer), wrapped around the main wiring harness under the dash. Unfortunately some of the sheet had deteriorated and was missing. The good news was, over 3/4 of it WAS there! I have kept the sheet safely tucked away ever since.
Through the years I've always wondered what the code entries meant. Folks with later models have some info available, as well as color code markings listed on their sheets. It seemed that information on the early models was lacking.
Recently Charles Turner posted an image link to a copy of a 1966 dealer order sheet he has. I got off my behind and scanned an image of my build sheet. While looking over the scanned image of my build sheet, I pulled up a copy of Charles' order sheet. I then realized the codes listed below the option descriptions on the order sheet coincided with the codes on my build sheet! While this may not be a shocking revelation to a few folks here, it sure was to me!! While I certainly haven't heard or read it all, I've never seen anyone mention this correlation before.
In order to put something together to reference in the future, I took all of the codes from the order sheet and cross referenced them to the build sheet blocks. This information was put onto a table. I figured while I was at it, I might as well put it up on the web. I created a page on a free host and it's now up for anyone interested.
You can access the page at:
1966 Mustang Information
Please be advised, this is a work in progress. Most of the codes are listed. Some build sheet blocks are not listed because they were unreadable or missing from my sheet. Repops are available to fill in the blanks, I just haven't gotten one. If you have the missing info and would like to share it, I'd be happy to add it in. Also, if you find any errors, please let me know. I only ask that you provide a reference to what you base your claim on.
I've also included some T-10 four speed information on the site, though not much. I plan to add to that as I find it. It's also provided me a more "permanent" spot to make the pdf file from the Shop Manual that I recently referenced in another thread '65 Shop Manual for the T-10
I hope someone finds this useful. I discovered my car was originally ordered with dual red band tires!
