82 240D - how many miles will clutch last?

[jimmypete]

I'm fourth owner of my 82 240D. From the paperwork I got with the car, it looks like a previous owner replaced the clutch at 70k. I'm at 150k now and it's still working although sometimes it does shimmy a bit starting from a dead stop. Also I can feel first gear grabbing a tiny bit when I'm shifting to 2nd. I'm putting it on a boat to New Zealand next week. Just wondering if I should take parts to swap out the clutch since parts may not be readily available there. Wondering if shimmy and 1st gear grabbing are early symptoms of failing clutch. Also wondering how many times that flywheel can be resurfaced.

Thanks for your help.
