Title: Transmission speed-o clamp - 70 4 speed
Post by: Yellow r code on May 28, 2025, 10:14:53 AM

Can anyone tell me the correct clamp this is in the picture. It's the one where the Trans bolts to the bell housing. NPD had no idea when I was ordering some items.

A Ford part or stock number would be helpful.

Doesn't look like speedometer, perhaps backup light switch harness?

First wonder if the factories installed such a clip or retainer. That would be the first thing I would check.

Don't think I have a copy of the page your referring to but isn't there a identification box that shows the part number there for item #14?

It is the backup light harness because the switch is mounted where the harness comes out on a 70 Hurst shifter in the illustration.

There is a clip for the B/U harness right at the shifter but not so sure about the one shown in the assembly manual?

clip number is 371166-s100  in the assembly manual.  Correct my fault, it is for the back up light switch. I have some problems with is car. I'm having a hell of time keeping up with it.

Unfortunately, Ford hardware part number, 371166-S100, is not listed in any Ford documents depicting its measurements. Another odd thing is that its use is shown as being used on 64 thru 66, and 70 thru 72 Mustangs but not 67 thru 69 Mustangs.

Unfortunately the clip number does not show up in the AMK guide to fasteners.
