All my bleeders cleaned up but one and I had JC drop one in another order. They are only a couple bucks. Not sure but you might find a match on the FLAPS Help rack. The cylinders are easy to overhaul. You'll have to hone them and check for any corrosion where the cups slide. If there is enough to feel with your fingernail its usually not worth the aggrevation to try saving them. I got one at NAPA. My others cleaned up. I don't mind buying new if needed but reuse what I can. A couple $$ here and there adds up quickly.
Just take your time and think it out its not rocket science.
The snows comming soon Good Luck
