Turning a c10 into a dually?

[Billet man]

I have a 1972 GMC truck and am wanting to make it a dually. Is this possible? If so all the help I can get would be much appreciated! Thanks in advance...

Possible? Sure. But your frame is a 1/2 ton frame, and people usually want dual rear wheels to increase hauling capacity. You'd be better off starting out with a 3/4 or even 1 ton.

Nowadays a lot of people just want it for the looks

Yes it's possible. When I built my 68 dually I had to shorten the frame 60" and weld it back together. Then later I swapped out the rearend to get rid of the 457 gears which required using the old springs.
To do what you have proposed if it was me I would find a cab and chassis and graft the back portion onto your frame. Whatever length you want.
Just my opinion. Don't flame on me or hate me cause my opinion is different than yours.

The 1/2 ton frame is gonna be your limiting factor than in it is so much lighter and that the front stuff isn't gonna bolt up as easily as you will hope. I have a one ton sitting out next to a half and the frame is not only thicker but it is way taller too[distance between the channels is greater]. Jim
