Went ahead and cut the plate in my truck. Cut it too small, had to take another piece out. I welded those back together. I ahve about an 1/8" of herculiner back there, so it was hot enough to be melted under the outer shell, just pushed it back into the weld groove with a chiselNever know it wasn't one piece from above. Billy is picking up some steel so we can make the brackets to hold the final plate in. I will seal it with RT and then touch up herculiner over it. I may pull all the what were once phillips head screws. They are rusted pretty much flat. Rather do it now than on the trail
Not a terribly hard project and will save LOTS of time if I need to swap the fuel pump one day.
