Check your ring width and bore diameter. The C 10 may be the one you need.

Brady,
The Hastings piston rings won't fit your A motor. The A is 1 3/4 bore and the C-10 is 1 15/16. Your best bet is to keep an eye on Ebay. Good luck.

I think I have NOS Rings for the A-Series Engines in stock. Will be back home after the first of the year and will check then.

I was wondering if you had anymore iron horse parts including rings thank you
