So, my grandpa has a 2002 Silverardo 1500 series, and my grandma who recently broke her arm was sitting in the passenger seat and was pinned in by a seat belt that locked up and wouldn't let her go. The more and more she tried to get out the tighter it locked up (on her broken arm), long story short they had to cut the belt to get her out. Being pretty good with cars I said i'd order the part and fix it, however im a bit at loss how to replace the mechanism in the seat to make it work, and what part I need. An ebay and google search turned up new belts, however they were three point and I think his is just a two point. Any idea, or if any one has some seat belts laying around i'd be ever so appreciative.
