Thanks for all the advice guys.
Its owned by a mechanic at an independent LR garage here in Scotland.
I mentioned all the areas you guys have mentioned to me, and not only does he say that there is no sign of rot, but he says that there has been no welding done to it either!
Its had a new clutch 5 months ago and just through an mot.
Regarding the axles, i have 2 new casings lying in the garage as i couldnt get what i wanted for them a few years back. Im glad of that now!
Anyway it sounds like a clean one so im going to look at it on Tuesday. I'll post pics if we get it.
