 Jerry,
 I just saw an add for a 13b motor (no year) PP for $1,000.00 Aust dollars
 which is
 about $500 US. However I suspect it's a racing motor - they do the PP
 professionally down here. I can enquire to the cost if you wish.

Thanks but no thanks.  I am looking forward to doing it myself.   Jerry
