Interested in your parts. Are you willing to sell 1 complete cylinder set, or everything together?
What kind of prices do you have in mind?

Have 2 piston and liner sets left. Call 563-379-1456 or leave message in my inbox.

The four groups I bought were delivered today. They look fantastic, old packaging but clean & perfectly pristine in the inside, with a preservative oil of some kind. Whoever buys the last two sets shouldn't be disappointed, and the price was OK. $250. a hole.
