Problem is the "stock appearance" as the later, non-folding seatbacks extend the seatback cover down over the attachment arms and wrap around the seat. If you convert the seat to a folding style the cover needs to be modified (basically cutoff) and finished out exposing the arm. Might look for an earlier folding seat to steal parts off of and modify yours. Remember it is more than leaving out the top bolts and the seat back does not latch. IIRC some of the later square bodies had folding seatbacks that did latch and that is where I would start looking.
