I purchased a 9Bolt complete rear supposed to be in good condition. When
I got it home I pulled off the rear cover to find cracks and holes in the posi unit. Looks like it was blown up at some time. I drained all of the lube into a 8"x8"x1" bake pan, and found about 1/3" of burnt disk materila and many small/large disk particles in the bottom of this small pan. So now I am assuming I need to replace this posi unit, or rebuild it....any out there at a reasonable price, or where do I find the parts for this. I'm, a handicapped Vet living on disability and cannot afford much. Any help will be appreciated....
Thanks , Ed.

The one I have is a 3:27...I will look fot the other one. thanks, Ed.
