Bell-housing alignment help

Those are some weird numbers. I think you can buy up to .021" offset dowels. I had a bear of a time doing my son's. I finally removed the dowel pins that were already offset and put in straight ones. Then did the dial in again. Was able to get it to spec then. You never really know what someone else has done in the past. PS I made my own dowel pins from 1/2 rod stock.
