I have the same motor and I needed the same parts (except the piston), piston rings (link https://www.ebay.com/itm/170930945421?var=470208408843 ) you need a 38 X 2 mm (1.496 X 0.079 inch) that is the size I needed should also be for you because they are the same motors and year frame, for a connecting rod I can’t really help you there, mine snaped in half and I had a friend weld it after we straightened it (still works fine).
Bob, that is a pretty common motor to be found at our meet swap & sell events. If you aren’t in a hurry, just keep an eye open for a parts motor. Now, an issue could be your location. Are you near any of the chapter meets?
