1971 Demon 17" Help

I have yet to finish this Barracuda. My plan is not to narrow the barracuda seat but to weld-in a donor, dart, package tray and and back seat support. I'll use and narrow the non-folding dart seat. I plan to have a huge package tray that extends the length of the back glass. Maybe mount some subwoofers. I removed those brackets since this pic. I posted that pic to show how I left part of the floor attached to the tub. You can see where I drilled out the plug welds. Those holes got welded up. I cut the floor back so i could continuous weld the floor back together on top and TO the outer flange of the frame rail which I actually folded over to gain another half an inch. Kind of regretting it all now that I am about 15 years older and wish I could just drive the car again. Good old hindsight. Nice looking Demon @J.B.

That would definitely be one way to take care of it!

Although honestly, I did a bunch of research and even some fitting when I was doing the fold-down seat conversion on my Duster because I considered mini-tubbing it for awhile and was curious to see how much more difficult it would be with the fold down seat in place. Ultimately I decided not to do the mini-tub, but just because I didn't need more tire than the 295's I'd already decided would fit and I wanted to keep as much of the "pass through" space as I could because of all the stuff I end up hauling around in my Duster. Plus it gave me a good excuse to do the "reverse tub" and push the quarters out a big more to give the car more curves in the back.

But like my post kinda showed, I really don't think you'd need to do much of anything with the seat itself. A couple of flat plates with threaded holes or nuts on the back, in the stock locations, would work and you would basically keep the seat within about a 1/2" of its stock location, it would shift forward just a little bit. The bottom seat is plenty wide to give that up. Then you'd narrow the pass through around the tubs. The factory inner panels would just angle in, instead of being straight down, they could maintain their upper locations and would just taper in to meet the new inner tubs. That would probably give you a triangular gap to fill at the front of the interior panels, but I think that's just covered in carpet anyway so it wouldn't be super hard to deal with. Then you'd narrow the security panel to match the new inner panels, same deal it would just have to taper down.

Ultimately I think that would be easier to deal with than fabricating an entire package tray, but I could be wrong on that point. I'd worked out how I would do mine, although on the Duster the factory inner panels wouldn't work because they're just plastic. I was just planning to carpet the tubs on either side of the seat and make up a set of inner panels that would also get carpeted.
