I just bought a 1985 corolla GTS hatchback with a completely stripped interior but I already have most of everything I need to replace the interior. I have an original set of front and rear seat belts with the motor retractors but having trouble remembering how they all install so if someone could post some pictures of how the seat belts and retractors installed to give me a template as well some advice it would be greatly appreciated. I think those seat belt retractors mount on the c pillar arms somehow but not completely sure. Anyway, thanks in advance.

they mount below the c-pillar, and the rear side cards will cover them once installed.
a quick google of "ae86 seatbelt" gave me a pic

They just bolt right in.
