I've had the same idea on putting a 60 - 66 truck on an 88 or later frame. The bed should be fairly easy and the cab may (or may not) bolt on close to the same mount pads. Once the cab is on, all the front end bolts to the cab except the radiator support which may need a mount point added to each side. Anyway, you can have a classic head turner with the modern ride. Keep us posted on what you do. I'm certainly interested.
