only thing on that side is the small spring. It goes from pin to shaft. It sits in the grooves on the thin pin and on the flapper shaft groove.so it doesn`t side off. sure you can use the rusted pin if you want. I didn`t know if it was flimsy or not.
Thanks i thought it was a,spring or clip. I did not know what it looks like. Do not think I still have it.
I knew a,spring or some thing when there as the small pin is,raised at the edge to keep it on it and the large pin / shaft is grooved for a,wire spring
Any chance of a picture of the Spring so I can get something?
