I was talking to the chap who runs the garage which has been working on the 75. Obviously using aluminium washers moves the corrosion to where the washer touches the bolt, so you'd probably lose the bolt head (like my gas boiler, steel bolt into an aluminium casting). He reckons a nylon washer wouldn't melt. Any other ideas?
When I ask him what the 75 will cost me he just says 'You can afford it'. I felt reassured, I've known him a while.
I've just caught two bats in the house and put them out. Hope I can sleep.
