A standard Dually (DRW) rear end is about 72" WMS to WMS (Wheel Mounting Surface)

A single rear wheel (SRW) one-ton 14b full floater rear end is about 67.5" WMS to WMS which gives you about a 2" tuck on each side.

A C&C rear end is about 63.5" WMS to WMS - I have been told that a C&C will work without a lot of frame work and I have been told that it wont - so that's not much help!

The SRW have an Outboard style hub and the C&C and Dually rear ends have the Inboard style hub - and I still am not sure what those are!!

SWR and C&C rear ends use the same housing, but different hubs, a C&C rear is a SWR housing with dually hubs.

The Suburban 3/4 ton semi-floater rear ends have different spring perch dimensions but you would usually end up cutting those off anyways with a drop kit.
