Did you guys conclude that the 14-bolt Chassis-cab dually axle was the one to use with single wheels. I don't care if the drums show. Just need the WMS dimension to be close to the AD truck's dimension. And, of course enough clearance between the backing plate and the U-bolts.

I have found a 76 c-30 CC axle but I haven't bought it yet.
