Gorguruga I think your best bet is to see if Steel is local enough to do it for you, he's a bit of an expert on these sh*tboxes
Call him for a price then tell him that you won't pay more than £60 labour for it - works everytime!!
Lol.. Might have to give that a go but I'm in London and I don't think he's close by. Plus he'll probably charge me double for asking foolish questions.
