I sent my '78 driver's side OEM FJ40 seat belt to Safety Restore in Westfield, MA. They advertise on eBay and the web that they will replace the webbing and clean/lube/repair the unit for $75 or so. I found a discount code on the web that covered the amount of the return shipping and then some, so my total bill was around $73. Seat Belt Repair & Airbag Reset - Safety Restore
They claim they will transfer the seat belt ID tag from the old belt to the new, but in my case, they did not. In any case, the belt retractor is smooth and silent and locks up as it should. They cleaned the plastic housing and every part. A worthy job by any estimation. See before and after photos. They rebuilt and shipped the unit back the same day they received it, so I'm impressed with the speed and service.
This service is not for the concours-restoration level trucks, but it also wasn't $300. I just wanted my OEM seat belts to be safe and nice-looking, and work smoothly, and all that was done for what I feel was a low price.
