I took the back seats out of mine so I can weld the wheel wells. I threw the bottom of the seat away, but can still get you pictures of the back pad and the clips on the body.

I have the same problem on both of my Deltas with the weatherstripping. Right now the rear floor pan has a 2'' thick square of ice on it welded to the carpet.

Also, the carpet is a messy job taking it out. there is 1/8'' thick tar under there that will crumble into a million pieces.

Also make sure water isn't coming in from underneath your back seat. the factory seams there have giant gobs of caulk where the wells meet the body side.
