RE: your PM Justin.
Here's some photo's of when we did the Kidney Foundation's Circle Australia Rally Back in '96. May as well put them up for all, Hope they are of some help.
16,000km's in 26 days! Boy you value sleep after that!
Canberra, before we left:
Dash. Wayne got the seats from a wrecker, I can't remember what they were from? They were reclining and very comfy (which is the main thing!)
Rally start in Sydney.
Tasy somewere. After the front right Tie bar nut came off
We put the perspex sheild on the grill when the Weber kept Icing up - We weren't running a thermostat... don't ask

It was also good for keeping the Dizzy dry. The cut out is for the oil cooler.
Somewere? after we cleaned it...
Ooops!!! To fast through a creek crossing in S.A. Big hole in the gearbox!
Involved a very wet night in a paddock changing the gearbox. Thanks to the F100 backup vehicle we had a heap of spares!
Funny thing was that we had to Tow the F100 out with the mini the next morning because it was so boggy - LSD helps
Somewere in W.A.
AKA - "Minimal Effort" opening her up in QLD:
Conclusion:
Build the car more for endurance than speed on an event like this. Mini's are pretty strong as standard, but there are plenty of small mods which are definitely worth doing (most of which have been mentioned). Hope some of the pictures are of help or enthuse you, I don't seem to have any shots of the detailed mods we did.
Please ask as many questions as you like.
