    Heater Outlet Hose for 5.7L V8 with 8A5 RPO Code (140A alternator)

    So, I am going to convert from the 105 amp alternator (K60 RPO code) to the 140 amp alternator (8A5 RPO code). Part of the conversion requires using a different heater outlet hose. K60 uses GM P/N 15708635, while 8A5 uses GM P/N 15727640. The problem is that 15727640 is not available anymore...
