heads up-may need rear frame rail

well, I am going to give you guys who is cutting up the Dusters and Dart Sports that I may need a piece of rear frame rail. My son and I got into this 73 Dart Sport a little more this weekend and found a little more damage. not surprising. Some rot back there on the rear frame rails. I may need a couple feet of rail back there on both sides. I havent decided whether to get a piece off a car or buy a piece of box or C channel and make it. so if you have about 2 feet of frame rail on the very back end on both sides off of a 73-76 Duster or Dart Sport available, let me know and we may be able to do some business. Price it. my zip is 41035. Thanks,Bill
