I was looking at that pulley. The problem I think I am going to have is with my crank pulley. It is only two grove and I believe this pulley needs a 4 grove crank pulley. I can add that and not run it with the a/c compressor rerouting the belts just like we did back in the day.

One question I have is the statement on the their web page it states under note
3-The BPE4016 is the same diameter as the original single groove style pulley.
Can you tell me how this is true? The single grove pulley does not have a 6 inch diameter it is basically a 7 inch pulley. What am I missing?
