drums won't fit over hub over Moser axles

Small bolt pattern drums will not fit big bolt axles.

Drill the 4.5 pattern .

Cut the register.

And they still won't fit. You will need to find backing plates and drums for a big bolt car. The backing plates have a different offset and the axles have a larger dia. flange that the small bolt drum does not fit due to the taper. You can drill your small bolt drums if you use redrilled small bolt axles. Again small bolt drums do not fit big bolt axles. Register or flange?
