1970-1974 Dodge and Plymouth E-Body Two Piece Trunk Floor Pan
Replacing a rotted E-body trunk floor without cutting off the quarter panels is the main advantage of this two-piece design. Chrysler built the Challenger and Barracuda trunk floor as left and right halves joined at a center seam, and this reproduction follows that layout, so each half can be worked into place from inside the trunk. The pans are stamped from 18 gauge steel, the same thickness as the original, and are manufactured in the USA. One order includes both the LH and RH pieces.
Installation Approach
Start by photographing and measuring the fuel tank strap supports so the new floor puts the tank straps back in the right place. Drill out the factory spot welds with a spot weld cutter, remove one side at a time, and use the old metal as a template for trimming. Experienced E-body restorers recommend fitting and tacking one half, then fitting the second half and checking your reference points before any final welding. Butt weld the seams rather than lapping them, which keeps the floor flat and avoids trapping moisture between layers.
Two-Piece or One-Piece?
A two-piece floor is the more forgiving choice when the tail panel and rear structure are staying on the car, because each half is smaller and easier to maneuver and adjust. It also lets you replace the floor in stages if one side is worse than the other. A one-piece pan makes more sense when the whole rear of the car is already apart.
Frequently Asked Questions
Do I get both sides with one order?
Yes, this listing includes both the left-hand and right-hand halves. You do not need to order the sides separately.
What gauge is the steel?
The pans are 18 gauge steel, matching the thickness Chrysler used originally. That gives the floor the correct weight and stiffness and makes welding to the surrounding original metal straightforward.
Do the quarter panels have to come off?
No, the two-piece design lets you install the floor with the quarter panels in place. Working one side at a time also keeps the trunk opening square while the old floor is out.
