Not sure about the density thing.... The 81-82R pan is metal, so I ended up paying a local upolstry/automotive guy $20 to put mine one... he had to stretch it over those metal tabs... he also glued it down nicely all the way around.... Don't think I'll ever have to take that seat off! The material they use for the cover is very thick compared to stock OEM.
