Update:
Right now, it's looking like the stainless steel water pump shaft will run around $75-$100. I'm still working on seeing if I can get them cheaper than that. In the meantime, I want to send out a feeler to see what you guys think. Would you still be interested in these shafts if they around about $75-$100. Or maybe the better question would be: what are you willing to pay for them?
