<VV> one piece dual pulley

[peter koehler]

145 cid Corvairs with factory A/C used a one-piece cast 
crankshaft pulley. Quite heavy and no additional harmonic 
benefit (don't put one on a 95 or 110 or 140 application). 
There is a casting number on it. I could provide that if 
you really need it. Remember that 1961 was the first year 
that A/C was offered as an option and continued up through 
1967. - Caveman Pete
