Replace Seat Belt 1987 B2000 Cab Plus

Hello everyone. I'm new here but looks like I've found a great place for info about my '87 B2000 cab plus I purchased recently. I need to replace the driver side seat belt. It's not obvious how to remove the panels to get to the seat belt retractor. Can someone help with info?

I searched and saw one article on here referring to a B2200 that said you have to start by taking off the rear panel and work your way around to the side panels? Is that true for my truck as well and can someone give a bit more detail as to how each panel comes off?

Thanks,
Bruce
