Dude I had to go to a few "help" sections at a few stores but they had an exact piece. I have an extra I can just mail you if you want. I tried the heat shrinking method but only had wayyy to big or to small. If you had just the right size tho I bet if would work great not even replace it. Just do yourself a favor and dont use a heat gun. The coolant elbows sealant really dont like it. Anyway I can mail you a piece or I can give you the doorman part# "still from china" and you spend $2.99 and get 6 parts. Just heatgun= bad bad idea
