Steve, thank you. Let em see if I can come up with one otherwse I'll look you up. Are they a standard roll pin or are they a special diameter? I sure do apprecite the offer.
Jack. I'm not sure if I understand the meaning of first sentence but I planned to get the motor together and use a dial indicator to center the moon cover to the cam etc, if the cover is within tolerances???? I'm hoping the ceterlines on all the pieces are true but I have to figure out how to measure them to get everyting as true as possible. I appreciate the heads up though, no doubt you're mentioning it from your own experience. At first blush I was just looking at bolting everything together. But as I got deeper into the project more and more I started seeing things tha will need alignments and attention. Your post just reasured my suspicions.Thank you. Mark L

That's 'cause I didn't attempt to 'splain my meaning!

Even when precise location of centerlines is accomplished (cam/spud/pump), perfect orientation of all of the items' axes is not within reason to measure or correct. Even high-end shops make some assumptions- that cam centerline is perpendicular to block face, etc. It's best to allow for this possible slight cam-to-pump angularity with a loose-fitting drive.

I prefer to dowel-pin (or otherwise locate) all precision-location engine pieces (timing cover to block, etc.), so the dial indicator work is only required initially.
