Despite all its benefits, a floorpan is a big honkin' piece of metal and therefore quite a bear to muscle into place. "The average floorpan weighs about 70 pounds, so it's definitely a two-man job and can be a bit of a struggle. The best way to shoehorn it in is through the passenger door," says Austin. "Make sure to remove the doors, steering wheel, and rear quarter glass before wrestling it in. The other option is to go through the windshield frame. This requires removing the steering column and rear seat brace as well, since the floorpan needs to be slid up and past the rear seat area in order to get the front of the pan to clear the firewall."
