Boss Belt

I have found an Autolite belt for my ’69 Boss 429. The part number is JB-375 and it has a “1-69” date code. It’s the correct length for a ’69 Boss 429 smog pump. My original alternator and power steering belts have full part numbers on them, along with the “1-69” date code. Is the Autolite JB-375 considered a service replacement belt? If so, is it concours correct?

The Autolite JB-375 belt is indeed a service replacement part. The OEM belt would have the full C9AE-8620-HI part number with the date code embossed into the belt.

Ford serviced the Autolite belts in three widths: 13⁄32-inch (JA), 15⁄32-inch (JB), and ½-inch (JC). The JB-375 is 15⁄32-inch in width and 37½-inches in length.

Although not assembly line correct for ’69, the Autolite service belts with the correct date codes are a rare find. Mustang Club of America Thoroughbred judging would give a solo credit for the Autolite service numbers if dated correctly for the car.

Scoop Holes

I’m restoring a ’69 GT fastback. Like many owners, I don’t like the fact that the hood scoop is ornamental and not functional. When I bought the car in 1979, it had a hole cut in the hood. Now that I am replacing the hood during the restoration, I have to make a choice. I have seen photos of “pie-holes” cut in the hood. Were any hoods factory or dealer cut to make the scoop functional, or is any penetration to the hood under the scoop strictly not original?

The pie-hole shaped opening is correct for some ’69 hoods. Later in production, the cut-outs were eliminated. My ’69 Mach 1 does not have the pie-cuts. If you are swapping hoods, be sure to get a ’69, not a ’70, because the undersides are different. The hoods will swap and function properly but a ’70 hood will not be concours correct.

Sticker Location

I have a ’65 Mustang hardtop that I show at many events in Australia. I have a reproduction window sticker to display with the car at shows. What is the correct way to attach the sheet of paper as it would have been done in 1965 by dealers? Was it on the driver’s side window or the windshield? Was it in a plastic sleeve? At the moment, my reproduction is just a sheet of paper. It would be great to get some advice so I can display it correctly.

The typical location was the driver’s side window at the rear of the glass (see photo of original ’66 Mustang). It was glued to the glass so the window could be raised and lowered, but that also made it hard to remove without damaging the paper. As a result, original window stickers are very hard to find.

Body Color or Bare?

In the process of restoring a Grabber Blue ’70 Boss 302, we’re trying to determine the correct color of the plate and bolts in the door jamb that holds the window adjustment plate. We’ve seen some in body color with natural bolts, but what is correct?

The bolts are clear zinc (silver) but the plates could be body color, argent, or bare steel. The plates were usually placed on the cowl area or the trunk when the car was painted at the assembly plant. This process was not always followed; the plates were sometimes painted argent or simply left as bare steel. Body color is probably the most typical if you cannot determine the original finish for your car.
