Extending the cab was something I thought of too, but like you said the body line on the front of the door throws a monkey wrench into it. If you got an early hemi for me, I could put it in one of these dodges and have it sold tomorrow. The dad of the guy who does my metal working in town had a 48 with a hemi in it. He wants to find another one with a three window cab and a hemi. I know where to get the pickup, but I don't know where to get the motor
