plans for the weekend

So I was thinking bout making a snorkel this weekend, like this:

and stripping all the fabric out of the interior. I've got a Wagoneer Limited, with electric seats, are there any suggested replacement seats, maybe made of plastic? that I could throw in ther for a decent price? and any pointers on that snorkel would be appreciated.

holy shat!!!! while stripping the carpets out, I found the reason so much water came in when I was in a creek this last week. The entire floor pan underneath the rear-left seat is rusted away!!! time to learn some welding skills I guess
