Adapting a flatbed to a 1981 gmc 3500 / k30

[Trucksareforwork]

Hey everybody:

I have a 1981 gmc 3500 that I’m pretty sure was a cab and chassis. It has no bed on the back. It was a srw truck that has been converted to drw sometime in its life.

Question I have is this: I want to put a flat bed on it, but am new to that game. Can I generally adapt any aftermarket longbed sized flatbed to it or do I need to find one that is built specifically for this truck’s frame?

What do I need to know?

The answer is generally yes it’s not too difficult to adapt a flatbed to fit on a particular frame. But based on your question, have to understand, if you get a flatbed with wheel well arches, they need to be in the right spot. Or if you get one that is for a pickup truck which doesn’t have straight rear frame rails like your (and all c&c trucks) truck, you may be cutting or adding to account for the difference.
Also afaik, most all c&c trucks have the same or similar frame rail spacing so they are more universal for all the different types of boxes and bodies that are out there.
