Hi this is kind of hard to explain but here it goes. On my front passenger seat the male buckle on the belt has a plastic trim piece that goes on the buckle mine is broken off. Normally I wouldnt worry too much but the plastic trim is what stops the belt from going forward in an accident does anyone know if I can buy it seperate or do I have to buy the whole buckle... I checked gmparts direct but nothing.

 

I bought my car like that. I replaced the whole seatbelt and buckle because I couldn't find the plastic trim. I don't remember where I got it though, but I had a shop put it in because I didn't want to mess it up since I had never worked with seatbelts before.
