[swamp rat]

I'm at work right now but go take a look in my build thread, i replaced both of mine on my 72, they if i remember correctly were manufactured by Yukon. There are 2 different sizes if i remember correctly, the bearing journals tell the size story, need to be able to mic them. I'm pretty sure still have both of my old ones but as my post states there is a bit of a lip where the bearings ride. I'm pretty sure i can find the part number. I'm sure any local 4X4 shop could order them but if i can help you with the part number you may find them cheaper on line.
