WTB - .020 over cast iron piston ring set (1965 110hp)

Good day!
This may be a long shot but both vendors I spoke with today either don't carry or are out of stock. I am in need of a complete set of .020 cast iron piston rings for my '65 110hp engine. Anyone have a set they are willing to part with?

Thanks very much!

Enjoy the Corvair!

Hastings are pretty good rings. I have had poor results with Grant rings twice. Bad quality

Very hard to find.
Given the large .020"or bigger gap of most new Corvair ring sets , you might try a single .030 over bore CAST Iron ring and see if it can be filed to a.012"- 014"end gap.
This is the correct range for a Corvair ring end gap.
I have done this in the past In a pinch.
I did use a 220 hone to help the ring break in easily.
This will not work with Chrome edge rings!!
One time , many years ago I even used a lightly used .030" 0verbore ring set to do this.
For a " Econo " street engine rebuilt
Turns out not much filing was needed.

Obviously, the end gap needs to be measured 1/2 way down the bore with the ring squared up with a inverted piston.
Due to the natural taper wear in a Corvair cylinder, if a used cylinder is being used.
