We were tearing down a stuck 425 ('64 Wildcat) and broke a piston. Anybody have an extra laying around ?
http://www.taperformance.com/pistons.htm they have them std/.30/.40/.60 but i don't know if u can just order a single piston or if u have to order a whole set
If you are tering it down; I would replace the whole set especially if it was stuck. Money well spent.
