Now you may know that the hole in the pic is to let water drain down and out the front of the sill. No problem I hear you say - take the rear plastic mud guard off from the inner wing and you shall find your screw. Well yes, but I had been avoiding doing this for some time afraid of the rust and holes that I may find behind, not to mention shearing the mud guard bolts!
Strong sweet tea and a smoke we’re taken, and nerves were steeled. To my surprise the mudguards came off easily and I found nice solid metal behind. No holes, minimal rust, no sheared bolts. A good does of waxoil is all that’s required before re fitting the mudguards.

Also found the old aerial just hanging there!

And of course the screw.
