Sorry about all the distributor posts, but wow.
Bought one from RockAuto in Dec.
Ignitor went bad after a few hours of use. They sent another unit on a warranty replacement.
Got it Thursday. Put it in, no spark. None at all.
My mechanic confirms - bad distributor. Man...
RockAuto will refund money, but will NOT send another distributor. Company policy of only one warranty replacement, then a refund only...
Guess I need to order from someone else.
