New Seatbelts for old Gtp?

[dirtyape]

I have read that you should replace seatbelts after an accident or if your car is over 12-15yrs old. I haven't been in an accident, but the gtp is 20yrs old now. Where would I buy new seatbelts for 1997-03 grand prix?
What do you guys think about replacing them because they are old?

Nope, never unless maybe if there was visible deterioration on the belts. Just keep them clean...

Right. I've seen them get so packed full of gravel dust they don't catch at all.

The seatbelts I've replaced came from the boneyard. Never went new, so idk bout all that.
