Casey’s Customs is at again with another budget chassis swap build. This time around, he’s chassis swapping a 1951 Chevrolet with an AWD, 6-cylinder 1999 GMC Jimmy donor and has set a budget cap of $3,500. He’ll chop the top on the Chevy, and will add airbags to the GMC suspension.

Editor’s Note: Casey refers to this build as a Rat Rod. While the Chevy sheet metal may be ratty, this is certainly not a rat rod, but a budget example of swapping a late-model chassis under an older car or truck body at home with normal tools and not much other help. For more information about swapping chassis and drivetrain, see our Body / Chassis Swap Overview.

Additional note, Casey uses colorful language on occasion. If you’re some sort of softie, or you got the kids on your lap, be advised.
