I've had a similar project bouncing around my head for several years due to the massive amount of modification needed I decided to build it as a model. Stock frame from a 54 (I have a junk one) Z'ed and shortened. Motor would be a Buick Straight 8 (Also have the motor) 10 inches Sectioned out of the middle of the cab. Square off firewall and cowl (Like a roadster should be). I didn't do it on the model but most likely section some height out of the cab as well, or potentially raise the floor to get the body further over the frame and closer to the ground. Shortened bed.. Never figured for sure what the scale measurement would be but it needs to balance out the massive Buick 8 on the front.
Ahh, also I've collected a 4 inch drop axle for the front and planned on running 16 inch wheels all the way around.
