MGB Flywheel resurface?

I finally got around to pulling my flywheel off the MGB engine. It has substantial corrosion on the clutch mating face, and possibly even some pitting. These are apparently irreplacable, so I need to find someplace that can resurface the thing. I cannot find any specs on how much material can be shaved off before it becomes too thin to be servicable. Assuming I can find a place willing to do it (which has also been an uphill battle, apparently no one really does this any more), I will need to be able to provide relevant info. And if it is pitted too deep for be resurfaced, then I guess I'm in the market for another engine?
 
You are stressing too much. Aluminum flywheels are available and offer faster revving and a weight reduction. You should be able to find used flywheels as well. Bruce
 
I've looked at those, and if I when I am able to do an engine from the ground up I may well go that route but right now I have an engine that last ran 12-15 years ago and I'm reluctant to buy a high performance racing flywheel for an engine that will probably run but is largely an unknown quantity.
Its free, it turns over by hand without any strange noises and when I had the pan off to replace the gasket last year there was nothing that looked concerning in the bottom. There is some surface corrosion in one of the cylinders (which I was able to see with my cheap inspection camera before it broke) so I expect there will be less compression on that one. Valves condition is unknown, nothing visibly wrong under the rocker cover but I'm not inclined to pull the head unless I experience something that warrants it. I'd gladly go with a used flywheel if I could find one. Local would be preferrable because shipping one would be painfully expensive, but theres not many small British cars (or parts) here in the land of full size pickups and big SUVs.
