I have purchased a 1990 Firebird. Unfortunately the rear shoulder belts were removed. I have all the parts but cannot find the instructions / diagrams to make sure they are installed correctly. I have two kids that will be riding there and would like the shoulder belts for them.

The "T" slides into a slot in the front and the bolt goes in the rear. The shoulder guides are held by two bolts on the edge at the top of the back of the rear seat.
