First off im sorry if this has been posted a billion times but i searched and couldnt find specifically what i was lookin for...

so, I have a 1990 rx7 turbo II and the passenger side belt buckle (the part that slides on the rail for the chest strap) is broken. its not the motor or anything about the rail its the actual buckle itself. right now there is a mounting plate that slides past the passenger so i kinda want to fix it. it looks like an easy fix i just need the buckle and i cant find it anywhere.

Any help at all would be greatly appreciated

Thanks!
