My 69 came with a 14023156CH stamping and I dont think it is correct.
What is it from and what is the correct one ?
Thanks all

Johnny, I believe the correct deep groove water pump pulley for 69 L78 is 3947824. At least that's the number I have written down in one of my files. Not sure of the two alpha digits at the end. Maybe somebody else can confirm the number, otherwise I could check to see if the numbers are visible on mine.

Thanks Don .
I will jot that number down.
Any idea what the one I have may be from?
It is a double pulley ( same size ) with a wide space in between the two grooves.
Thanks, Johnny.

I can't help you with your current pulley Johnny, perhaps post the number in "Tag Team".
