Another bucket seat question

[87SaberSeven]

History. Back in the late Sixty's I raced a Cooper S that I had fitted with what I was told were bucket seats in the same pattern as those used in either GT 40's or Cobra's (poor memory at this age). They were very, very tight fitting around my(then slimmish thighs). Made from fiberglass. Low backed. Anyone remember these? Anyone have a source? Great seats.
