Hmm ok. I'll have to check what the diameter is, mine is the leadmine kit. I suppose I could always have my machinist open up the inner diameter a bit.
I've got a couple of hot rod projects too, and a couple of C-body 8 3/4's from the local yards because they seem to show up on occasion and they're practically a steal, $160 for a complete 8 3/4 with brakes and a center chunk. Since the C-body axles can be cut down I figured the kit was a good investment, but I haven't had the need to use it yet. Figured it might come in handy too if I 4-link my duster, just to make sure the housing stays straight when I weld on the brackets.
