Thanks for the offers. I haven't thought this through as I'll need to either hire a van or pick up to collect it, or fit it on site and cut up the old one there and then.
North Ayrshire is preferred as I'm on the west side of Glasgow - sorry John! Shug, I'll drop you a PM once I've sorted the logistics out - I assume it won't be a problem if it takes a couple weeks to arrange something?
