Hi, Dave.  Yes, he did the rebuild on the 25D dizzy I'm running now.  It's =
a points distributor with a Pertronix modification, so luckily don't have t=
o deal with the entire distributor.  And agree, he does good work. =20

He knows distributors for British cars like no one else.  His work and rebu=

But there should be no side to side play; and the plastic piece should be t=
ight on the point cam.

 If the plastic piece is loose, its probably just time, heat and vibration =
vs cheap plastic.
