This is my '48 5 Window. It started as a 3/4 ton long bed. I put it on a shortened S10 frame (106" wheelbase)with a 350/350 combo. I sectioned the cowl 5 inches to match the bottom of the fenders to line up with the rockers. I took 21" out of the front of the bed. Next up is to get the core support mocked up well enough to start fitting a 1950 Buick bumper and grill. Still figuring out how extreme of a chop...
