I did ask and its his Dad that made it. He said to make it worth while though he would have to charge about £300 to get the rack, fabricate the bits, powdercoat it. Thats 3x what I paid for it, and for me it would be too much to pay. If you'd be happy to pay that then I can pass on your details and see what he says.
Um, in a word... no I don't need a rack that badly yet
Thought that would be the case If you can find yourself a fabricator, you can get the rack from Halfords for £90ish and then get them to weld up the supports. I can send you pics and dimensions if you do.
