[VB] redux: Porsche Pulley

[sam williams]

I did a search om thesamba.com and found a reference to pelicanparts. I 
went there and see they make repro inner and outer generator pulley parts.
Are there other parts I need to make my pulley smaller?
My 63 singlecab has a 3.88 R&P so I only turn 3000 RPM at 60 MPH, the 
oil temp will go up when it is hot (>85) outside.

I happened to have an aftermarket VW pulley where the bushing was not welded into the rear half of the pulley. Took it apart and the bushing fit perfectly into the 356 parts. Don't forget the shim washers.
