Hi all,
I have bought rings and spacers from Dave Reed a number of times it's best to phone to see if he has them in his extensive stock ~50,000. See his web site for more info. http://www.ringspacers.com/
The top ring grooves always wear more than the others, since you have broken/stuck rings you probably should pull all the pistons to put rings/spacers as needed.

Hi- Thanks. I pulled no.2 today and no broken rings but they are stuck in the compressed state. Oil rings plugged. I have not been able to remove an oil ring without breaking it.

I have only pulled the two pistons that were frozen to the cyl. sleeves. Pulling pistons has not been much trouble(for my son!) but putting them back in seems like it will be torture. Jim
