has anyone tried the non AC Delco or Denso ignition coils?  How have they held up?  How about the fuel injectors?  There is a fairly big diff in price with the parts at Rock Auto.   
I know with my Old Astro van for example, everyone swears by Delco ignition parts, and for the most i agree, the delco ignition coil and cap rotor do last longer then the cheaper autostore parts.
