s I cant find the part at Home Depot or a local plumbing supply house. The only number I could find is on the delta brass plate US Patent 3674048
Hi Ken, Thank you for your question. If you have a 2 or 3 handle tub/shower faucet the replacement parts to stop a leak would be the RP1740 stem assembly and the RP4993 seats and springs. I have attached the parts breakdown below for this model to help you with the repair.
