well the gas tank is and always was behind the seat, if you look carefully at the pass. side you can see the vents in the tape ahead of the door, the tape covers them pretty bad on the drivers side. the door may well have been changed, the cad is off of a truck with a 501 I cant say I expect it to be original, but if it miss matchs but I have doors that are so good that this guy was the first time it was in the rain in 15 years and the doors filled up with water, you know there is no rust and the fire wall was smoothe, but it had alot of hole, I'm guessing for the air brakes.
Thanks
