Upper Radiator Hose for 1984-85

[akorna]

Hello!  I've searched but can't seem to find an interchange part number for the upper radiator hose.  Current set up has two different flex hoses connected to the radiator cap adapter midway.  I've found a listing in Avanti Parts, but it only covers to 1983.  Not sure why they would be different since there was no real changes in configuration until the 1987 Monte Carlo chassis.  All I can see is the change from the A6 to the R4 compressor.

Getting back to this thread.  Unfortunately 1700928 and 1700929 aren't even close (bought both- I believe these are for 63-64 with a surge tank eliminator kit.)  It must be a combination of the location/orientation of the R4 A/C compressor and the angle and diameter of the thermostat housing on the Chevy L69 "HO" 305.  I've  tried other molded hoses from Camaros to Caprices and Monte Carlos with no likely fit, even with cutting sections out.  What is needed is hose #1  with a 1-3/4" ID at the radiator with the same diameter at the inline filler neck, and hose #2 with a 1-3/4" ID ending with a 1-1/2" ID at the thermostat housing.  I've ordered some Dayco Flex hoses, a reducer and a inline filler neck.  I'll posts part numbers if it ends up good.  Here is current leaky setup.

Those look like two universal flex hoses..  All you need to know is the length and hose end diameter
