I just wanted to post up what I came up with to bypass my heater core for my 1998 Dodge Neon Race Car. I used a heater hose part number 19438 and two screw clamps from Oreilly auto parts. The hose is almost the perfect shape. Just had to cut a little off of one side. (Shown in picture below.) I hope this helps someone else who needs to bypass there heater core.
