8 1/4 axles do not have "pumpkins", only the 8 3/4 does. All other axles have rear inspection covers/plates that remove from the rear for servicing the gears.
Here is an ad posted yesterday for an 8 1/4 with 3.21 sure grip for $400 by 340sport. I have bought parts from him a few times, and he is a good guy to deal with.
