I think they are interchangeable, between the C-5 and the C-4. A friend of mine has the C-5 M. Collari and needed a new piston and sleeve. He was looking for the collari C-5 parts and couldn't find it. So he ended up ordering the C-4 piston and sleeve (I believe Collari modified) online for his engine.
