Maybe you could look at some sort of overdrive. Either a change to a modern 5 speed gearbox or a bolt-on unit. I think a higher diff ratio would probably be better as you Europeans do not seem to take your vehicles bush-bashing and the unnecessary crawler first gear is just along for the ride.

Yeah, a 5-speed conversion like you did seems the way to go. On the other hand, the engine I bought is fitted with a fully rebuilt SM420 4-speed gearbox already, so maybe an overdrive/ diff swap would be a better option? We'll see later.

There isn't a lot of bush left in Western Europe to bash through - this is about as rough as it gets
