OEM distributor..
Ordered a couple of rotors for my 1985 318s. Tried putting them on and the shaft is bigger than the rotor hole. Called Dave at Hurrikain Marine...he is baffled too. He is researching for me a bit. He says there are only two type caps and rotors and I ordered the correct one. Maybe they packaged them wrong?

....He hasn't had any complaints like mine.
Here's the cap and rotors.

Do you know something we don't?
I know they made some engine changes in 1985..
By the way Dave is a super guy if you need parts. He follows up with his customers if you have a question.
