I found a local guy on craigslist that's got a pair of gray seatbelts out of a 92 chevy truck. Couldn't pass $10. Still need to find one more driver's side.
for the rear seat belt on the second row passenger side I'm going to use one of these. It will be my 2 year old's permanent seat. I used one of these in my old blazer for my oldest daughter when she was younger.
