Stevens 190d back on the road with a new diff

I am pleased to inform that after a while off the road Steven's 190d, the white car in the very first road trip is now back in action. The whine from the diff had got worse and worse until it was decided to retire her until a replacement diff could be found. This happened just before christmas when I bought a car that was getting scrapped and used that diff.

We have also had a bumper collection of used oil so stocks are currently high, I really must start planning another veg powered trip !!!

Anyone got any ideas or suggestions ?

Ideas so far have been Iceland although I would probably rather avoid the problems cold weather could cause, Morocco (up through spain), and Malta. We can't go through Italy because its not legal and we will of course have to check with any countries the trip will go through.
