cab and chassis with a reg bed?

what all does it take to make a cab and chassis have a regular 8 foot bed on it? Just bought two cab and chassis reg cabs one is a 06 6.0 and the other is an 08

The cab an chassis frames are 4" or so narrower. You will have to redrill the box mounting holes to line up with the frame or build brackets to make it work. The rear axle is narrower aswell (dually). The box bolted to the frame with the wheels centred will leave roughly a 6" gap between the rear of the cab and front of the box. You can buy smc filler panels that match the body lines and fill the gap. Unless its a 10-12' chassis. Fuel tanks also between the frame rails after the rear axle.

There may be more but that's all I can remember for now.

Thanks

this is what the filler looks like Dustin

Anyone have a link for the filler. We just bought reg cab & chasis. We just got a bed for it Monday. Will definitely be needing that filler.

Yeah the filler looks like a simple way to make it look decent, doesnt have to be perfect by anymeans

only thing that bothers me on these trucks is the black plastic cap instead of a third brake light LOL

There's a guy around here running a reg cab 7.3 dually. Kept trying to figure out what looked odd about that truck. Axle was narrower... tucked up inside the fenders. Now I know why!
