I have a 1991 S10 Blazer 4 door 4WD and none of the seat belts work. They don't retract and if I pull on them they never engage and pull all the way out. I would like to replace the front and rear belts but my question is what years are compatible with my blazer?

I found some belts on LMC truck that look like they would work but are more than I would like to spend. I found some on ebay from a 1998 but I don't know if they will work. Any help would be appreciated. The current belts are blue but I am not picky on color. Thanks.
