what is the part number for the 2 heater hoses that run into the firewall on the left side (passenger side) thanx

thanx , but i have asked and stopped at napa, auto zone, and pepboys with pics they all give me a different answer, i would buy all of them and then see what fits and return the others but want to buy online cause its from 10 to 20 bucks cheaper per hose thanx anyways
