As far as I've known, toe boards and the pan under the rear seat
hasn't been available in reproduction as was the rest of the floorpans.
I came across this recently and thought I'd share:
A little pricey but nice to know it's available if needed. A "full
" floorpan usually runs approximately $100. so basically you're paying another $100. for the toe area and $100. for the under-seat pan.
I don't know that the center
of this piece is simple "cut and paste" for all years....probably '75-'81, pre-catalytic converter.
