Just acquired a 91 Suburban, the 'classic' body style. Wondering if I could retrofit some seats out of a 99-03, with the integrated seat belts? I'm not familiar with any additional mounting points these seats may have for the seat belt- are the belts totally self contained in the seat? Anybody done anything similar or have any knowledge that would be helpful?

 

The seat belts are totally self contained. So obviously you would want to use the strongest hardware available and possibly reinforce the body where you bolt them because the seat mounts will be taking the full force of the occupants if there ever is a collision.
