Was wandering about putting a regular dually bed on my flatbed. A previous owner had some dog boxes welded on the flatbed body and I really love the dually bed look. A customer of mine has an 86 dually that's he dying to trade for my bed but I'm not sure if it would fit. I know about the gas cap/ door difference.
Any info is appreciated.

Is your truck a dually?

Yes sir

Is it a cab and chassis truck or a truck that originally had a dually bed on it. If the later it will work, former it will work but the bed and cab will have a gap as the cab and chassis were longer.
-
I'm not sure. As far as I know it's always been a flatbed. The flatbed has dog boxes welded on and possibly the skirting.
-
Not sure if the bed is a modified factory one or complete aftermarket?
-
Cab and Chassis trucks didn't come with a bed. That flatbed was added to it.
What is your VIN decoded to?

I've never seen a factory K20 dually.

I've never seen a factory K20 dually.
I was going to wait and see if anyone else pointed this out. Either the truck is actually a K30, 1 ton being the only way to get a dually OR there has been some parts swapping in its past.

CKL24...
Chevy 4x4 3/4 ton with 165 hp 350. Cab and pickup box.
Someone must have converted it. Well that could simplify things. Convert it back and get a regular bed? Or keep the dually conversion?

CKL24??

First 5 characters of vin.

Got ya, I wasnt sure, because with only 5 digits, that could have stood for anything.

CKL24??
I was thinking CHUCLE-24. For some reason people spend all day pointing at me & laughing.

Looks funny with the 3/4 ton wheels in front and dual in back
But it should swap over
Measure the wheelbase of both trucks carefully and take a good look at the frame
Some cab and chassis trucks had a flat frame at the back

Check the overall width of your duals (outer wheel to outer wheel) versus the overall width of the duals on the truck with the dually bed.
If I remember correctly,
With duals swapped onto a single wheel 14-bolt rear end (C/K-20 rear axle), the total width (outer wheel to outer wheel) will be narrower than duals on a dual wheel 14-bolt (C/K-30 dually).
I'm thinking that the dually bed will physically swap fine, but the outer dual on your truck will be set back within the dually fender...

I was able to track down the original owner of the truck. It was a standard k20 lwb. He was the one who built the flatbed. Someone afterwards did the dually conversion.

Ahhh and that's the ticket right there.

so.... are the front wheels bud wheels?
if you look at the back of the rear brake drums is there a lot of room to put a socket and ratchet on the brake bleeder? if theres very little room then this would indicate a cab and chassis rear if theres more than enough room then it would be a dually rear. if you have regular wheels upfront the inside tires should like up if its a dually rear if its a cab and chassis rear the outside tires should line up. take some pictures and we can help tell a story about the truck
