Nice reply 72 Blu.

So you are saying any axle up to 60'' width, can be used in an early A-bod if you use the correct back-spacing?
All you have to do is re-jig the perches.
I only said this about the Demon/Duster because I have worked on those with factory steel wheels.
If you fit a 57 inch axle in, there is still plenty of room so a 66/67 axle will also work.
I heard folks going to wider 60 inch B-bod axles in with custom made wheels, just not in the UK?
Folks here like to use a correct 57inch A-bod axle in an early car as they can get some wheel choice 'off the shelf'.
