I need this too - lets both reply if we find something :-) I had an extension welded on mine and it worked for a while but I just got new 295s on the rear on some Torq Thrust IIs and now the extension isn't long enough - also my door action isn't very good and I worry that is because the extension i had welded isn't straight - so this time I want to get the factory extension - would like to buy online but I think I might end up at a dismantler.
