Hey guys, looking for a little help. I just replaced the heater core when I added an a/c system to my 1997 Tj 2.5l manual. I ordered the Gates 19004 for the heater to thermostat connection and the inner diameter is too small at about 5/8. The old hose is a Mopar 55037372 with almost 3/4 ID. I am having trouble sourcing this stupid hose. I searched the forums and couldn't find that answer as well. Your guidance is much appreciated.
