Can't locate cooling hose from Valve to heater core.

Hi,

I am having a tough time finding a replacement cooling hose from the heater valve to the core.

My 1995 325 Convertible has to hoses (right and left). The right hose is 64211394292, but I can't even find a part number for the left hose.

RealOEM shows it on the drawing, but does not list a number.

Part #5.

Any ideas how I can find/buy this hose?

Thanks.
