Looking to do a dually conversion on my truck. Would the rear axle assembly from this truck fit mine? It's a cab and chassis truck, so I'm assuming the axle is narrower. Are the frames narrower on cab and chassis trucks?

Cab and chassis truck frames are narrower at the bed. Also, as for your differential, the center section might work. The axles will not because the C&C trucks have a narrower axle too.

 

That's what I thought, but just wanted to make sure. Thanks!
