Anyone interested in 83 Pace Arrow Tear down and Rebuild?

Place the pan in place, place 4" wide strip of FRP over lip of pan and up wall 3" mounted so that it is removable then permanent install FRP over rest of wall overlapping the 4" strip below. That will shed any water. If there is a concern about water possible getting behind the FRP waterproof the wall first, then install the pan and FRP over the waterproofed wall.

To remove the pan first remove the 4" wide strip of FRP and that will free the pan for removal.
