The seat belt retractors are not hard to replace, you have to take off both the front and rear sill plates, then take a T-50 socket and remove the bottom and the top atttachment point of the seat belts. then pop off the trim piece that covers the inside of the B piller and that is where the retractor assm is(its part of the seatbelt) and it is attached by a T-50 bolt also, and it has wires pluged in to it. un plug and replace. go to tascafordparts.com for a great deal on parts. there cost on those are around $100.00 ea. good luck
