I've got some health stuff going on
during the first couple weeks of Feb.
2012 so orders placed will be slower
than usual getting out.  Sorry for any
hassle.  JT
If you are doing a pushrod seal job or
something else that require removing
the early piston pin clips I'd
reccommend you buy a spare or two.  
They fly and/or easily get bent.  
Because of this tendency I've stocked
some as a convenience.
