Build Sheet(s)

Mark,

The pink build sheet suggests a two-tone paint job - black on the bottom and white on the top. I'd be interested in hearing if you find any evidence of this. Sounds as though the hood was white.

Also, there should be a tag on one of the bolts that attaches the rear gear set to the center carrier. The tag will have some info regarding the gear set; ratio, build date, etc. Maybe there's something there that further explains what an H code rear end is? Typical Mustang rears used number codes for standard gears and letter codes for limited slips.

<font face='Comic Sans MS'>Perhaps those two holes are from a trailer hitch installation. I installed a light duty hitch on my new '66 Mustang F/B back in the day. It bolted to the rear bumper, and there were two arms that curved under the gas tank, bolting to the trunk floor just forward of the tank.</font id='Comic Sans MS'>

Just wondering if the "BL" on the build sheet could be "back up lights" as that was still an option in 66....? Something that I recall from a visit I made to a Ford assembly plant in Canada was that it was not unusual for a car to be pulled from the assembly line if a problem was encountered... once the problem(s)were fixed it was put back on the line to be completed... could that be what happened here?

I thought back up lights were standard equipment on 66 Mustangs?

sixfiveGT,

Back-up lights were changed to standard equipment for 66. The 1965 build sheets had an option code of 2 for back-up lights in the 8th box from the right on the second line:CLOCK - LITE GP - B/U LITE - SAFE CONV

The Remarks box usually indicates the typewritten notes at the bottom of the build sheet - if there was something special about the car. A couple of my export car build sheets, with comments at the bottom, use a 2 in the remarks box; I believe to indicate the number of comments.

Early dealer order forms for the 1966 model year, with a print date of June 1965, still had the option boxes for the back-up lights and rocker panel mldg., but these boxes were deleted from the October 1965 printing of this same form (Form FD 1841-M).

I too, have been curious about the rotation number. The one thing I would have expected to change on this car (with so many changes) was the rotation number. Especially after having been delayed for three weeks. The idea that it would be re-inserted into the line-up with the same rotation number seems highly improbable, but both build sheets have a ROT of 106. Curious....

appreciate the correction, was looking at the 65 option sheet instead of the 66.... you certainly have a wealth of information on these sheets... thanks for sharing. It is curious that the ROT number stayed the same... when I was at the Ford plant they had 7 cars that had been pulled for various reasons... we were told that it was possible to cause some confusion down the line depending on when and why the vehicle was pulled... but for the most part they were able to get things re-sequenced without a problem.

Wow

Would you mind asking your dad if he remembers my car 5F09K6.......... <img src=images/icon_smile_big.gif border=0 align=middle>.

Seriously tho, your dad might be the answer to everyones prayers. Why not ask him if he wants to sign up as a consultant. I bet the guys here would love to ask him a few questions.

Cheers

Mark

Mark,

You’re dad is a great resource! Please do ask him to participate.

Sounds like the static line punchcards were an early version of the metal buck tags. It would be interesting to see a sample.

Does your dad remember the meanings of some of the radiator support codes?

Every couple of months huh? The phone works both ways.

So, I'm finally officially a member now, and can start posting. So, I'll try and cover a couple of things on this Build Sheet mess real quick.

You didn't tell me all this stuff when we talked. Your car was made less that 2 months into the ramp up of the 66 model year, so it is a very early 66. It wouldn't surprise me if you had quite a few left over 65 specific parts.

The second "D" shaped hole on the driver side under dash, is from the 65 emergency flasher relocation. It should just to the left of the choke cable.

The "Two holes forward of the gas tank on the trunk floor (punched 3/8" in diameter)" along with a few other things said (UCA holes, heater holes) and the lag date on the build sheet, really made me think. The UCA holes are just that, holes used to relocate the upper control arm, improve camber and lower the center of gravity of the front of the car. The two holes next to the heater motor hole sound like battery relocation holes (to put it in the trunk), the the 2 hole in front of the gas tank sound like a fuel tank shield that tied into the roll cage. These were all items found on some group 1 and all group 2 racers. The problem is the C-4 wasn't, and Shelby didn't order up the Group racers until December 65.

I know some individual racing teams did order K cars and have them reworked at Shelby. Your best bet would be to contact them and have them look up the VIN and see if they ever did work on the car, you could possibly have a vintage racer. But the C-4 still sticks in my head. Unless it was running some smaller circuit tracks, I wouldn't think a race team would differ from the 4-speed. But, those are just my thoughts.

William (Bill?),

Would the assembly line have made these modifications, or were they performed after the car left the plant? If the line performed them, how were they instructed to do so? The build sheets don't appear to contain any codes that would direct such customization.

Pete

Everyone just calls me Bill,

These modifications would have been performed after it left Ford. When Shelby started building it's racers for Ford, they would order small quantities. They would do a complete tear down of the car, and rebuild it to FIA or SCCA standards at the time. Individual race teams could also order cars and send them to shelby on their own dime.

I can't say with 100% certainty that this car was a racer, but some of the present day indicators do point that way. What I mostly hear of is some past owner had a new set of tools and a garage, and the next thing you know, you have a shelby clone. I do think it would somwhat difficult to clone or fake a Group I or II racer though. There isn't really a lot of information available about them. Sure, if you were diligent enough you could find enough information to make some educated decisions, but there would still be many unknowns about how the cars originally left Shelby.

I still say the best thing would be to contact Shelby and get thier input. They would know original hole diameters and placement.

Welcome, Bill!

Mark described you as a “Mustang Team Worker”, but didn’t go into much detail beyond that. What function(s) did you perform?

It would be helpful to the rest of the Mustang community to have you share your first-hand knowledge. This particular thread deals with build sheets (Mark’s in this case). Perhaps you can elaborate some on how they were generated and used – perhaps some of the meanings of the codes if you remember.

Mark mentioned a static line sheet that followed the car on the Body and Paint line. Metuchen used a metal buck tag plate. Would this have served the same purpose?

He also mentioned crayon markings on the radiator support and other parts of the body. You might explain this process and the meanings of some of those markings.

In other words, anything you wished to elaborate on would be appreciated and would be helpful in moving the knowledge base of the hobby forward.

Pete
