Does anyone have any pictures of a stock '32 Ford 3 window seat showing the curved side wood supports?
Here are the specs for the bottom seat pan. the following measurements from an original 32 3-window seat pan: front overall width = 37"; rear overall width = 39 7/8"; front to back overall length = about 22"; side-to-side distance between bolt holes for the two pan-mounted seat tracks = 31". . When the back board on mine was redone ... cabinet grade birch plywood was used. The entire back panel was made to be the same size but just one board, not a series of 7 pieces made into one back rest. I believe my version is stronger and was easier to duplicate.
I actually made the patterns OFF mine for a HAMBer ... I mailed them to him at least ... 2 or 3 years ago My interior is finished now ... ... I could TRY and another trace a set ... for you if that would help.
