How To Replace Floorpans

The new pans are held in place with aircraft-style Cleco fasteners,which are temporary. Then Rust Busters begins the busy task ofrosette-and bead-welding these pans into place. Rosette welding is aplug-and-fill form of spot-welding.

Anytime you have to weld sheetmetal to frame members, such as thetransmission crossmember, holes are drilled...

...and bolts are used to pullthe sheetmetal flush with the frame member.

Once bolted flush, the pan is welded to the framerail extension andtransmission crossmember.

There's a lot of welding associated with floorpan installation. It'sbest to rosette-weld as much as possible, then grind the weld smooth,which gives the installation a factory look. You want to see welds onlywhere the factory made them visible (such as a bead weld).

The rear-seat floorpan looks like this out of the box. It needs to betrimmed and tweaked for proper fitment...

...The rear-seat anchor point hasto be removed from the old pan and welded to the new.

Our installed floorpans look like this. For corrosion prevention, weuse self-etching epoxy primer/sealer, then body sealer at all the seams.Underneath, we use a high-quality, bulletproof sound-deadener andundercoat.
