Bellhousing Dowel Pins - offset dowels KEYWORD - Free Shipping on Orders Over $99 at Summit Racing

I had to go to a local machine shop to have them made at the time. Runout where? on the face or the bore?
In my experience, those .500 dowels are for a Chev, they would not fit in my block. The good old mopar performance ones that i used fit perfect and they measure at .497. Those dowels from mopar performance are in my treasured special parts drawer.
