...one part for 1980-1996 truck and Bronco. Is the mounting the same on all those models?
No.
They might be selling 1 aftermarket kit that's applicable to all of them, but the original belts are VERY different, in many ways. Broncos are always different from Fs, and even Broncos' belts changed through those years. But Fs changed more...
The early F shoulder reel is at ear-level, which is probably what yours has. Later, it moved lower, like Broncos, but still isn't interchangeable (according to Ford). In the late 80s, a large door-jamb button was added, and then it disappeared by the early 90s. My stash has grown since I took this pic:
The buckle is specific to the chair style - not the body (F/Bronco). Captain's chairs & low-back buckets (as found in many Broncos) get a hard molded guide that makes the buckle stand up on the floor. Most other chairs (benches) get a soft buckle (often with a shorter plastic guide) so they can follow the chair as it's adjusted fore-aft.
