I know this may be a stupid question to pose, but i want to add seatbelt pre-tensioners to the rear outboard seats in my 97 SE. The wife is bugged that I can't take the kids carseats in my car anymore since getting the Bonny cause there is no latch and no pretensioners. They were not common issue for that year, does anyone know what year they were, or if I can use them from some other GM car. I'm not sure how unique seatbelts are or if they can just be switched between models. On a side note, my 03 Buick Rendezvous also does not have them for the rear seats and has latch only. What a pain, carseats are much easier to move about if you just have to use the seatbelts with pretensioners. Of course i'd rather not have them at all but save that argument for another time....

Stupid question i know, but any help would be greatly appreciated. Thanks!
