Stock 3 pt seatbelts - 72 Blazer

[buckkoo]

I'm trying to find a set of blue seat belts with the shoulder harnesses for the front.

From what I've heard 72 Blazers used two separate belts. One belt for the lap and a second belt for the shoulder.

Apparently blazers used one hole to mount the shoulder harness, while other vehicles in 72 used two smaller holes, so truck or car belts won't work.

Does anyone have a pic original 3 pt setups?

How about the retractors? Are they just a long, truck style on driver side and then a short, car passenger style on the passenger side? Are there any special brackets required?

Thanks!
