searching for correct piston pin c clip retainer for old sealed power piston

i’m trying to figure out where to buy the correct piston pin c clip retainers for my stock style late 80’s Sealed power 2369p pistons with floating pin. One of my clips is bent so i’d like at least one but would prefer to replace all of them.
I’ve searched online and this forum and the ones i’ve seen suggested are not the same size as the ones in my pistons.
