Thanks for the quick responses, everyone!

I will try to get in touch with Frank at the e-mail address listed above, however, I'm not sure if I need such a good quality piston ring -- stock would do, but I'll take pretty much anything as long as it will work.

Thanks for the help in looking, captinjohn, it would be great if you could find a suitable for ring for me, but if that fails, I guess I'll be opting for the "best rings in the country"! [sm=biggrin.gif]
