Morris Minor Owners Club

I've started rebuilding Rosie at long last, I seem to remember some of the fuel tank screws were shot. What size screw are they? ESM lists tonnes of screws but doesn't say what they do and Bull Motif don't have their usual helpful 'you may also need' bit on the fuel tanks

Sorry, ignore me, just noticed that ESM have which screws to buy. Need more sleep I guess
