Sorry I havn't come back with any more info, the car is requiring some rust repair, and I have been waiting to borrow a welder. I say the car will be back on the road soon, but not being the worlds fastest worker it is likely to still be a couple of months.....
However I would go 944 MC (In fact that is what I have done
) , and from comments on this thread and others that would be the general consensus for the best MC to match the 944 NA brakes.
Good luck
Cheers
Jeremy
