KitchenAid dishwasher part needed!

[therhett17]

Help! Just acquired a 1990s KitchenAid dishwasher and the cap for the rinse aid dispenser broke off upon removal. This part is discontinued and I can’t find it anywhere on the web. Does anyone have one they’d be willing to part with? Or know where I could source one? It’s Whirlpool part # 4171221. Thanks!!

If this one is at all compatible
