Thrust Bearings

[Cooperman1]

I'm just doing some work on a 1965 Cooper 'S' for a friend. He has run the centre main bearing quite badly and this has scored the thrust faces of the crank so that they need machining. Now, here is the problem. You can only get standard and +.003" thrusts now whereas you used to be able to get +.003", +.010" and +.030", which meant that cranks were always salvageable and you could fit 'S'-cranks into non-'S' big blocks.
I've got one set of +030" thrust which I am going to mill down to the right thickness for this 1965 car and I've found a supplier with just one set left.
Anyone got any ideas or know of any available.
If not, I wonder if the +.003" ones can be metal sprayed on the steel backing face and ground/milled back to the desired thickness.
This could become a real problem for all of us if we damage our cranks, and hot Minis with comp clutches are hard on crank thrust faces. second-hand ones to take no more than +.003" thrusts are not that easy to find and a brand new 'S' all-steel crank is £mega.
