Thick versus thin piston rings

Post by jnbmoore » Sat Sep 08, 2018 6:54 pm

Just went to install a set of standard piston rings for my 65 Dream and discovered the top two were too thick. Checking Bill Silvers book, he discusses thick and thin rings. The rings I had were 13010-266-000. Obviously, my pistons take the thin rings. What is the correct part number for these rings and are they the same as the rings in the CL and CB77?

The rings will have a -275- number. Same as CB and CL
