Well I had a quote from Dale at Holeshot for the link pipe and fitting kit, and when freight, import duty and VAT is added it's a non starter. However thanks to the guy at SP Engineering, I've located a stainless pipe bender within 5 miles from home. Showed him a picture of what I wanted, "Piece of cake" was his reply. Just what I wanted to hear, so just need to sort a can and let him get on with it.
