The previous owner had a "professional body shop" do all the body work new quarters, trunk pan, drivers side floorboard, one inner wheel well and the new viper yellow paint. But what he didnt tell her was he was just gonna lay the new floor pan in over the old rusty one, put a few tack welds in and smooth some bondo around to look good but from underneath you can still see all the pin holes from the old pan so I cut it out and butt welded the new pan in the correct way. The grey primer is where the old pan was laid in there.
