OK, Can you measure the distance from dual wheel hub WMS to the backing plate flange on the (single wheel) axle?
Then I'll measure the stock setup on the C&C axle to compare that to.
then the difference is how much the drum needs to be shorter, and I can get a good guess in the Napa brake parts catalog if another 14 bolt drum is close.

Thanks,
Grigg
