Try Home Depot if you lucky you will find one but the best way is to call Delta at 800-345-3358 explain your problem or they may ask you to send the pictures they will identify the cartridge and will send you one for free no charge to you, good luck.

Thanks, I got the part # from them and found one on eBay !

It was part # RP32104

Why you didn't ask them to send you one for free Delta faucets parts has life time warranty? here is the image of your cartridge, Thanks.
