Does anyone have a picture of the bolt and nut for the main harness hold down loop? It is to the left of the instrument cluster. Part number 56303-S4 for the bolt and 34659-S2 for the nut.
Item 18 and 19 in the picture.

A description with references is available in the Forum's Library under Mustang Hardware Spreadsheets 69-70.

That's nice, but I still have no clue what they look like.:P If I read your chart right, the bolt is also used at the automatic shifter, and the nut is not used anywhere else in the car?
-
The nut 34659 is shown in the AMK 2014 catalog on page 54 .

Maybe this will help?

The bolt looks very similar to the picture. The "visible" difference is length. Head style, lead point tip are the same. Head marking is unknown. This type bolt is called UBS by Ford, Unified Bearing Stress. That is a hardware design that has an slight undercut on the head to act as a locking device.

Jim, were you in the fastener business ?

Nope. Designed and built Air Force tracking station, satellites for the USAF, NASA and others; went into military logistics, and then (after we won the cold war) into commercial business planing, scheduling and inventory management. We used a bolt or two here and there.

Well, here's a picture of it. I found my automatic shifter ones. The markings are UBS on the outer rim, and WRB in the center.

The dimensions would be nice. Be advised that UBS screws/bolts are measured for thread length only from the underside of the head. Do not measure the lead point (sometimes called dog point).

Great picture. Not a big deal but for future reference the maker mark is RBW. It is easy to confuse when you don't know the beginning letter as in the circle of a bolt head. Its all good.

That would be short for Russell, Bursdall and Ward the manufacturer
:D

In the Forum's Library is a topic that shows drawings of many of the bolt head markings used on Mustangs. The pages are part of the "AMK Guide To Ford Fasteners - 1966-73" compiled by Max at AMK. (Used with permission.)

Want a "zap? I recommend "Cave Creek Chili Beer". It has a jalapeno marinating in it.

The thread portion is 9/16".
