Ok im getting real frustrated, I kept reading on different forums that 96 and 97 mustangs did need the new heater/coolant tube and nipple, and 98 didnt. Well I tried my hardest to get my intake in there and its hitting the heater/coolant tube in the valley. Autozone or oriellys cant even order the part, i gave them ford numbers. Then I went to the dealer and they wanted 30 bucks for the water pump oring and 60 something for the heater tube!!! and they couldnt even find the nipple thing. What gives!
