Replacing distributor rotor -- do I need an adapter?
At 100,000 miles, appears to be time to replace both distributor caps and rotors, according to my independant tech. Says "green stuff" is growing in there . . .
Looked at Parts Shop, has the best prices around, but I'm confused since there is listed a "rotor adaptor" listed in addition to the rotors themselves.
Does anyone know if in fact I need the adaptor?
