drums won't fit over hub over Moser axles

Dr Diff, thanks the reply.Without buying different axles, what are my options ? I've had people tell me to cut the axle hub on a lathe and others say open up the drum register.We talked to a local street rod builder and he said that this is a common problem on Ford 9 inch rear ends when going to higher strength rear axles.He said that he opens up the drum register.
