Well I'm looking into getting an '88 K5 with a shot body but allegedly good frame and running gear. I'd be swapping teh body of my '60 Willy's Pickup onto the K5 frame. The wheelbase I've found for the Willy's is 118" and the K5 is 106.5". The difference is obviously 11.5 inches. The stock length for the Willy's is 184" and the K5 is 184.8". So length is basically the same. So what I'm wondering is if there's enough room on the frame behind the rear springs to move them back 11.5 inches? The body will be gone so I don't need to worry about chopping sheet metal. I'm not sure yet if I'd be able to or need to move the front axle to fit the cab on and not hit the firewall on the engine. Does anyone have good measurements or drawings of distances between parts of the frame and drivetrain? Thanks a bunch.
