This is the floor three years ago, after I used a wire wheel to remove the rubberized coating the PO brushed on. You can see how much rust damage there is.

This is the day I cut the old floorpan out.

Here I’ve needle-scaled the frame underneath and sprayed it with encapsulator, wire-wheeled the edge of the floorpan, and sprayed it with weld-through primer.

This is after welding the steel pan in along the edge of the seat support and transmission tunnel.

Here I’ve got the rest of the perimeter welded in and sprayed with primer.

This is after the entire floor and toepanel has been welded in and ground smooth. The sheetmetal got wire-wheeled and cleaned with acetone, then sprayed with etching primer.

Here’s the seat support recent and adjusted to fit, sprayed with etching primer inside and weld-through primer on the edges.
