Hi Ian - I struggled to find someone, but in the end I asked a guy who has a small garage in southport who has looked after the car for most of its life.
He has a guy who does welding for him, and met up with him - seemed to be a good guy, so it’s currently with him having sill / floor work and a full respray
Will let you know how it looks when I get it back if you like ?
His name is Dave and he’s on 07836 263473
Cheers
Stuart
