The way we did it in the junkyard was take the front doors off and throw um in the back. Then cut the front of the door jambs into the floor all the way to the dog house in either side. Then cut the door jamb at the front top just behind the windshield all the way over to the other side and just yank the whole front end off with the wrecker. Bout 30 minutes and you're right on top of the motor. Unless of course you wanna save the van.
