Thanks Drew. Your suggestion is a good one and I will certainly consider it. I have replaced floor pans in an El Camino but they weren't as far gone as this truck...I was hoping to get a reference dimension from perhaps a hinge screw hole to the bottom of the hinge post panel...or something along those lines. This whole floor is just gone...I mean it ain't there. I know the hinge post bottom replacement panel must weld in first...then the kick panel and floor pans can bolt together and everything can be checked, tacked , and rechecked until it is just right be fore full welding. If I get the first part in the wrong place, all the parts will be in the wrong place and the door won't fit...I know there are many out there who have been in this spot. What did you all do? Thanks, Jim.
