Hi,
I'm getting ready for Vintage Air AC install on my 69 coupe. I thought I had the right pulleys already, but my pulley numbers don't seem to match up with any data I found. My three groove crank pulley has this number:
14023145 BA
i HAVE A THREE GROOVE WATER PUMP PULLEY, TWO OF THE GROOVES ARE THE SAME SIZE, AND THE THIRD IS A SMALLER (oops sorry) diameter groove. It's numbeer is 14023156 CH

Do these mean anything to anyone?
Thanks
RJ

actually I just noticed that on the water pump pulley, the two groove part of the pulley has the #14023156 CH STAMPED ON IT, AND THE SMALLER DIAMETER GROOVE APPEARS TO BE spot welded to the 2 groove part and this smaller groove has part #14037740 DH stamped on it. Help please
