Jonathan, Excellent and well done! That must be such a relief to finally 'get to the end of the road' with the car. BTW isn't your inlet to the air filter in the Winter setting? The end of mine ends against the exhaust clamp although I wonder if that is correct. I would have thought that cool air would be better during our Summer months. My rocker box has a yellow sticker reminding the owner or mechanic that an oil filter with an M10 thread is required for my 1100cc engine. I wonder if those stickers are available?
