Still looking for a flange coupler for my international harvester 824 4WD tractor. The part number is 3134 228 R1. The flange coupler is located on the front of the driveshaft that connects to the front differential. Seems like an impossible part to find. I'm sure there's a tractor sitting around somewhere that we could salvage that part from. Contact me at tac1756@bell.net thanks Thomas
