Early Barracuda "Heavy Duty" Rear Seat Backs?

I reupholstered the rear seat back and bottom for my '65 using a Legendary kit last Fall. The seat back uses no foam, only jute and cotton batting. It is very heavy, most of the weight comes from the solid steel back, springs, hinges, and latch bar. I thought I'd hang it on the wall to save space but quickly gave up on that idea. Here's some pictures from the process. Getting the dip just right in the center is difficult, as is figuring out exactly how many layers of cotton batting are needed to get it just right. Had to redo the cotton batting a coupled times, it took less than I first tried. Legendary has videos online that help.
