Does anyone know if Corbin or similar to a reworked 3TJ seat padded out a bit for comfort?

Ah and does anyone have a knackered seat for me to buy?

I don't think they do - They're an american company and the 3TJ wasn't imported there.
But you could get a silicon gel pack and some seating foam (try http://www.pentonvillerubber.co.uk/aboutus.html" onclick="window.open(this.href);return false; ) they recover it

I have a seat not knackred but make me an offer!
