390 Idler Pulley
On my '75 F-100 with a 390....I have a horrible squeal coming from a pulley on the front of my truck. I have replaced the idler pulley that is located more or less on top of the engine because it was loose on the shaft....didnt solve it. Now Im thinking its the other idler pulley on the driver's side a little lower between the a/c compressor and the crank pulley. It has factory integral a/c and power steering. Can anyone tell me this part number or where to buy it? I have searched everywhere online and can't find the right one for sure. Not sure if it is D0AZ-8678-C or D1TZ-8678-A Is there a difference?
