Broken set of cast iron rings (missing one top compression ring) that fit a 283 or 307 Chevy V8 that has been bored +.030" to a 3.905" bore size. There are 7 top rings, 8 second compression rings and 8 oil rings. I used one ring to replace one I broke during assembly. $15 plus shipping, will fit in a $5.95 USPS Priority Mail Small Flat Rate Box. Checks or money orders only please, I don't use Pay Pal. Please send me a PM if you're interested, thanks.
