For those that have done the full floor pan replacement what are you doing about the rear edge at the rear seat along with the driveshaft hump (circled in red). I know all the pans are stamped after a el Camino so it’s different than a Regal. Looking for some input as I get ready to tackle it in my car. I’ve seen some that were cut and welded kind of low just looking to see if anyone else had any better suggestions.
