rebuild a torque converter?

Are shops still doing rebuilds? I got an old converter that came out of a 340 car. Supposed to be a high stall converter. I know its not much of a converter, but it will get my car going.

Problem is that its been sitting for something like ten years in the corner of the shop. At one time it was full of ATF, but who knows whats in it now.

Should I,
A: try to wash it out with a few quarts of cheap auto tranny fluid, as in fill it up and dump it out.
B: Get it rebuilt?
C: Throw it away and buy a cheap off the shelf?
