What thread are seat belt bolts??

[PeteyDaMan]

Ok, this one is driving me crazy.
I few months ago I bough a 3 point seat belt kit from XV Racing and I'm finally getting to install them in my 71 Charger
I have all the original seat belt bolts but I'd love to be able to chase all the bolts and holes as....well....they're all 50 years old and need it.

Any help on the thread pitch and/or a source for replacements would be greatly appreciated.

Thanks
