Your a sheet metal artist Trenton, beautiful work!
What is the reasoning for a double floor (if I'm reading it right), even though you have allowed for drainage, I would think it would be inviting a rust issue.
Like Ryan said your work could be in demand on this page....
well the existing floors are so thin that something had to be done. the drivers has several holes but the "hat channel" was not terrible. yeah the best way would be to remove the floor pan and weld in the new sheet metal but in my mind this started out as a patch, it kind of got out of control

with the sealer between the two layers of floor and the spray coating thats in there I'm hoping it won't be a problem. this is really a fair weather wheeler for me as it will never have a roof, doors or heater so not a lot of snow wheeling is going to happen, i don't see it getting wet often and it parks inside the heated shop.
i've only ever done one floor before in a 1973 Camaro and it didn't turn out anywhere near this nice so i think the idea of removing the existing floor and ending up with a Flintstone Jeep was always in the back of my mind so laying this one on the old sheet metal was a security blanket. now that i got the basics of the bead roller and flanging down next time i'll just cut out and replace the floor... i hope thats not too soon.
