I went to a foam shop when I was redoing my seats. It seemed that the
quality foam was very expensive and they told me it would break down in a
few years. The springs in the seats were rusted away to mostly dust,
although the seats weer somehow still comfortable, but that was after 40
years of abuse. So I went with new springs. They're the non-original, a
little higher than the original, but then I am not as tall as the original
either so it works for me. I got the springs and the kit from Moss, via
British Parts Connection, at the same time I got the re-upholstry kit.
Everything was included in one or the other kit except the hog rings. As I
recall, there was burlap to cover the springs, and padding (horsehair??). I
added about 1"inch of some seat padding (wasn't foam, got it at Ealmart I
think) to the back and bottom of my wife's seat - she likes to be able to
see over the dash.
