Proto ratchet question

[PacificaVette]

I need some help with a really beat-up Proto 5449 1/2" ratchet. For anyone who owns one of these beefy ratchets, can someone please measure the screws that hold it together? The ones from this ratchet were mangled. The ratchet looks really old---I hope Proto didn't use some weird size back then.

Thank you so much GJers!
