LOL, It's not an impossible project by any means. Mostly it's cleanup and reassemble, from what I can see ( not that I've seen all that much of it). Chains, bearings and seals if your lucky.
I never picked up on the OZ thing, haha, but if you ever need a hand, and if I can help from over here in Western Canada, just fire me a pm.
Does it have single 60 chains on the back 2 axles?
