S13 Seat bolt threads?

M10x1.25

A tap won't fix it if the threads are stripped though. Cross-threaded, yes. Stripped, no. Maybe a helicoil or weld a new nut to the bottom of the floor.

Well, it's weird, because I can thread the bolt by hand about 1/4" into the hole, then it just stops. But if I get a socket to thread it in, then it goes in, albeit a little tough.

Then it's not stripped, the threads are just damaged. A tap would fix that right up. Stripped threads are when the threads are COMPLETELY pulled out of the hole. A tap won't fix that because the hole is too big at that point to re-tap threads into. The drilled hole is smaller than the OD of the tap. It has to be in order to have material to tap threads into. Once you pull the threads out the hole is now the same ID as the tap's OD so there is no material for threads.
