I'm working on mine and can't quite find the correct thread. I don't want to force a tap in it. It did have a broken bolt, which I removed w/o issue and it runs through a 10-24 die but a 10-24 tap seems to want to cut threads.
Anyone have any knowledge of these threads?

If your are asking about original Cobra production parts:
Do you mean the three small screw holes in the steel fabrication (very early Cobras) or aluminum casting (most Cobras) used in the lower radiator circuit? Original parts should have British BA series threads I believe. Reproductions have whatever thread the maker of the part liked or wanted.
