$125 · Pair of Chapman Fiberglass Seat Forms

This is a matched pair of heavy-duty fiberglass seat forms, made by Chapman, for building custom bucket seats for hot rods, sports cars, boats, etc. The hard part is done. They can be bolted to sliders, upholstered with foam and vinyl, leather, or cloth, to make strong, durable bucket seats. The dimensions are per the photos - 21" high from the base to the top of the seat back, 16" deep (front of the seat bottom to the seat back), 16" wide (seat back) and 16" wide in the seat bottom, tapering to narrower at the seat back for fitting around shifters, parking brake, etc. The side bolsters are 3" deep. I originally bought these for my (very!) small sports car project, but they were a fraction of an inch too wide.
