Hi all,
just a note on my experiences, albeit a bit late, on the subject.
I received replacements from Moss for my TR4a years ago, and more recently
for my TR6. One car is in restoration and one car was wrecked in a head on
collision. I still have both seats, each having run two seasons on "hard"
use (10k miles or so each summer). Both are still intact, though showing
some stress cracks. My personal guess is that while new, the seat foam gave
greater support to the diapraghm causing shower degeneration...
