So I cut out the door step and now I'm trying to figure out what sequence to do the repairs.....I'm also trying to decide if it's a better strategy to remove the entire floor panel or only the parts towards the outside that are really rusted. It would be nice to have complete clean non rusty floors but I can't decide if the outcome is worth the extra effort as the panels I have won't do the entire floor, I will have to patch in a few of the missing pieces. When I did the back panel, it was only after I had removed the old one that I found I could have bought a repair panel for just the bottom couple of inches - that would have been FAR less work than changing the whole panel and I'm pretty sure the results would have been just as good, maybe better. Like Binky, I could have bought an entire new floor and welded it all in one piece, but when the car was sold to me I was told the floors and sills were ok......and they might have been when he first started on the car 8 years before I bought it, who knows (but I doubt it!)
