running a narrow rear end in cc dually

Looking to see what guys are running one I found a narrow one measures 44 1/4 not sure what everyone is running and any pics of setups

i have heard a rear end out of a 3/4 ton surb works nice

the narrow rear end you are looking for is the P-30 14 bolt, it measures 63" from wheel flange to wheel flange, they came in the Grumman vans and on the cab and chassis trucks, they are a bit harder to find and thus worth a bit more than a regular 14 bolt.
