Alternator pulley for L79 with Power Steering

[Nick Mesich]

I just added Power steering to my 1966 L79 350hp 327, no air conditioning and of course the last thing I thought about was the Alternator pulley. Everything is installed, system bled and was looking forward to running her ths evening when I was putting on the belts and noticed that the Alternator belt was rubbing against the back of the new Power steering Cast pulley. The Alternator belt prior to the power steering install lined up on the forward pulleys away from the engine.

Does anyone have a picture of the correct Alternator pulley that I need for this new set up, where I can purchase one and possibly a part number?

My current Alternator pulley from Alternator outward, fan, 1/2" spacer then single pulley.

I was hoping to drive the car this weekend but I guess will have to wait again.

Thanks in advance for your assistance.

The correct alternator pulley is GM #3829387. It's 3-5/8" OD. It's still available from GM for about 58 bucks, GM list.
