Hi James and Andy
Thanks for the suggestions, I will in time take them up and sort out a stainless system, but have decided to take Stuart Read up on his offer for both of the of the boxes in steel as a stop gap until I want to spend the money on a new stainless system, having committed a fair amount to the project already this summer (a fair amount of welding/respray/retrimmed seats/new hood etc).....
