I am in Florida escaping the wrath of winter and need to know the dia. and thread size on the hollow headlight bolt for a 1934 Ford. I want to order a die to retap the threads and forgot to measure before I left ..Thanks...

No direct experience, but looked on Roy Nacewicz webpage (www.fordbolts.com) and it shows them as 1/2" - 20. If you want to confirm it's part# R-92-02 on page 30 of their online catalog.

I think its bigger than 1/2 20.More like 5/8 18.But double check.
