Early WRX seat belt buckle bolt?
 

Hihi.

Picked up some early WRX seats minus the selt belt reciever buckle thing...imagining it would all be the same. Except the WRX seats are the ones with bolt already there & just the buckle & washers/nut are attached. Seats coming out & donating the buckle are the ones with the nut already installed & its a bolt/washers that holds the buckle on.

Can anyone tell me the thread size of the nuts? Been searching online a bit & 7/16"x20 has come up for the bolt size but hoping someone can confirm before I go buy a nut to fit it.

Cheers.
