TC-5293 Swing Arm tire Carrier to TC-2961

I bought the bumper and swing arm a few years ago. Over the course of the last few years, probably because I didn't seal it correctly, the internal parts of the pivot rusted out. I contacted Body Armor 4x4 to get the parts to replace it and was sent a box of parts. When I opened the box the only thing that was in the picture from the manual AND from the emails from the company was the castle nut. Nothing that was in the parts list and a whole bunch of nuts, bolts and washers. The information they sent me listed their parts and another option, I went with theirs since that seemed to be the thing to do...since its their equipment. Does anyone know where else I can get the parts?
