The gear for your distributor is listed as a .468" ID on the MSD website.
The page on the MSD website for your distributor
does not say anything about an oversized shaft, but it also says nothing about under sized, therefore I am confused as to why they did that?
I know it will cost you more, but you will probably be better off getting a steel gear from MSD. Don't let them talk you into a bronze gear unless it is your only choice. They wear to quickly to suit me and I don't like the idea of all those particles roaming around in the engine.
I have compiled all of the information I can find on the MSD site for your distributor into a single PDF file that I will try to attach here. If you cannot access it and would like to have it you can PM me your email addy and I will email it to you.
