Floor Pan Questions

I got the entire floor pan and a partial rear quarter/trunk extension/trunk floor assembly for $500.

The back 6 inches of the passenger rear quarter/trunk extension were cut out and sold to somebody else so I will have some non factory seams in the trunk. I'll have to do those last after I get better with the welder. I hope they got a lot of money from the previous buyer for ruining that quarter and the trunk floor.

Unfortunately the driver's rear quarter/trunk extension was rusted out on that car, but my rust is very small on that side and I think I can just patch it.
