WIPAC S210A SAE R66 Mounting Nut

[tylerite3124]

Can anyone tell me the size of the metric hex jam nut that fits on the mounting stem of this reversing lamp? No one who I have taken it to has the answer. The picture below shows the stem I mean. Thanks for any help!

PS The system will not load my picture, Sorry. The mounting post is 1/2" (13mm) in diameter and the thread looks like # 13 or # 20 but it's not. So I'm assuming it's metric since WIPAC's were made in England.

Rick It's 1/2" BSF X 16 Tpi We didn't use metric until the 70's

Thanks for the info. I never would have guessed it would be BSF given that most British fasteners in the 60’s were SAE.

You can still find odds and end. The nuts on the original starter solenoid for example and the screw that's part of the adjusting setup on the later seats that goes into the base are two that come to mind. And I be all LBCs of the 60s have one here and there as they and contractors used tooling as long as it worked to avoid buying new.

IIRC, the screws that hold the lenses to the back-up light frames are also BSF. I had to buy some a few years ago and think I found them on eBay for just a few dollars.
