What bore and # of rings might help somebody find them for you.

If you need 4" bore and 3 compression rings per cylinder the hastings set is 2C702

Hope that helps,

Denis

I've got a set of unused rings for the stock D17 gas. I bought them before taking my engine apart and starting the rebuild. During the process I found that the sleeves were scored pretty bad and the ring end gap was around .25 inch. So I went with overbore sleeves, pistons and rings.

There are part number 70230091. I paid around $50 for them. You can have them for less, just make me a private offer. I can send you a picture of them first.

If your heads were like mine, you'll need to go with an oversize kit.
