If your overflow hose exits on the drivers side, you probably have an aftermarket radiator. Do you have the parts numbers on yours? They should be on the passenger side, top of the radiator.
I purchased them from here. I have had good luck with the company and although prices can seem average to high, the shipping is the cheapest I have found.

Hello I am looking too see how the overflow hose clips attach to the radiator. There should be
two clips that hold the hose against the side of the radiator. Thank you!
