help needed

Hi everyone, we’re looking for a mechanic who can help with our 1972 Commer PB Highwayman in South Lincolnshire (near Spalding) as our previous mechanic didn't really understand older vehicles. If anyone has recommendations for someone suitable, we’d be very grateful, thank you.

Just bought a resto project spacevan. Which wasn't the solid body to work on lead to believe. Screen pillars door runners and both footwells are nigh on disappeared. The chassis and engine and box are Good, but where to start and where to get pillars from ????
