Today I took apart the very leaky front hub, and replaced one of the seals. However, I'm guessing one of the others (which I don't have a spare of) is also leaking, particularly on the other front hub. I'm not convinced it'll stop leaking, but it's probably worth a try.

The front grille is now red, which looks better - photo to follow.

I also replaced the ignition barrel with a new one, so I have a spare ignition key at last. I was going to paint the rollcage, but it's sort of snowing, and I really can't be bothered! So I'm going to take the afternoon off.
