It sounds like your plate (the one that the points and condensor screw in
to) is somehow slipping. Just replacing with a Pertronix may not fix it.
Also, the Pertronix will work on a 25D, it's what I have in my car (my
aplogies to the list -- I typo'd the other day with '45D'). The part number
is LU142. Northern Auto Parts (http://www.naparts.com) sells them for about
$60. I have not had mine in more than a week, so I don't know about the
reliability. I'm keeping all of the old parts in the trunk. It's a
completely reversible operation and only took 2 minutes (really!).
