Where can I buy a single piston and rings for my to-20? Tore my to-20 apart to find out why #3 cylinder wasn't firing. Found a broken piston. No scarring, no other visible issues. Fatigue, I guess?
The piston has Z120A405 stamped on top. The bore is 3 1/4" as best I can tell. Thanks for any help![/img]

Z120 is original Continental stampings. The original bore was 3 3/16". Measure the piston. Now if the piston measures 3 1/4" then Mahle/Clevite sells their pistons and rings that are 3 1/4". I have that kit in one of my TO-20's.
 
I have 4 of the 3 1/4" pistons with rings on the shelf in the shop. Sorry email is not working so I'm not sure how to connect with you. Maybe post a wanted add in the classifieds, I should be able to connect with you over there.

I'll vouch for Crazy. I've gotten a few pieces off of him including a set of pistons. All has been exactly as he said they was.
