Will a 66 b-body 8 3/4 fit without cutting?

Just to rehash some the 67 and back are the narrowest of b-body rears-and as mentioned all the charts fail to state that.The 64 and older have the crappy bolt on drums,also with any of them the difference in perches is enough I would move them to do it right.With the wheelwells of the duster and demon it actually makes a std. offset wheel look and sit about right.
