Kev did you ever get that rust problem sorted out?
This might not be a lot of help to you as its in Oxfordshire, but there is a hive of little businesses I've discovered at a little place called Little Clanfield (its a couple of miles south of RAF Brize Norton's airfield), these businesses are all dedicated to vehicle restoration.
They mainly do classics, Frog-Eye Sprites, Jag XK 140s and the like. I've been dealing with Peter Baylis of Clanfield Coachbuilding (
http://www.coachbuildingoxford.com/) - Don't be put off by his web-site!. Peter is very personable and easy to talk to. Give him a call if its not too far away, and ask him if he or other little businesses at Little Clanfield could help.
Peter and the on-site auto painter (Mick Blewitt) are dealing with the wire-wheels for my vintage MG and "Cash speaks" or so I'm told (whatever that might mean!)
I'm going to be approaching them regarding another job on a 1980s vehicle that I'm going to post an article about in these forums later - maybe later today.
