What rear is this?

Roy, that rear you have, are the axle tubes a small diameter where they come out of the center casting, and then get bigger? I found a rear in my stash like that, but the spring perches are further apart then "A" bodies, and has a large spring center hole, like for the rubber isolated springs.

PS: I don't thing the ring gear carrier from a bolt in axle rear will work in a "C" clip rear. At the very least, I think the axle end gear would be different.
