Front Seat Belt Retractor problems of the 2001 Ford Ranger

The drivers side shoulder belt first locked up, then it pulled all the way out and will not retract. I took the vehicle to the dealer, but they did not take the rear door apart to see what caused the trouble. My children received a phone call in early July that the part would be in around 23 July. To this date, Aug 7, I have not received a call yet. I have called to local Ford dealers to find even an off color belt, but none are to be had. I fell unsecure, and even guilty driving this vehicle without a seatbelt since it is a law in this state, and I have to drive on an army post which is the law there also. I have also tried everthing I can to get this fixed. I even took the door apart to see if the mechanism could be fixed (which was more than what they did at the dealer), but it is un-repairable. (I have 20+years experience as an army mechanic) I would have even tried to switch the belt with the passenger side, but it will not work (the truck is a 4-door and will not swap out). Thanks for your time.
