The first time I saw this idea was at HAMB:
https://www.jalopyjournal.com/forum/threads/rebuilding-the-stock-bench-seat.909740/I will be following his lead.
However, I think I am going to build the bottom of the back so I can tip the bottom up to get to under seat storage.
Seat Measurements: I measured the spring base ignoring the rounding of the corners and the narrowing at the back (for now) Cut a rectangle of 20 1/4" x 54 1/4" Note: your measurement maybe different.
Seat Back measured 21 3/8" x 50 3/4"
Nothing exciting here, accept when I put the base plywood in and a 3" pillow with a piece of plywood for a back, I FIT, the pedals feel good...there is hope!
