Ok i have tried searching this and didn't find anything. I am trying to find the part number for the u-joints for the rear drive shaft in my truck. I bought some that the computer at the parts store said were the correct ones but they were like half the size. I will be home on mid tour leave and need to fix this before going to visit family. truck is one in sig

 

for the automatic neapco number 2-0054 and the 6 speed 3-0486
