Need to get a model number for this delta faucet

[Floyd Yancey]

I need to repair this faucet, need model number or repair kit, or cartridge number that I can pop in. Can’t find it on the delta site. Have three in the house. Please help

Here’s the kit. You won’t need the Orings.

Be careful taking that large nut off. Don't force it or you'll be replacing the faucet
