In Need Of Some 8 3/4 Technical Info

He didnt have any A body 8 3/4s left, he was really almost bought out of everything.
I try to look at all of this in a positive light.
I know that $100 is a good price for just the pumpkin. Its not the spring perches that are the issue, The whole assembly is 5" too long. And can I adapt this assembly for disc brakes if I cut the tubes down and get new axles?
