Mark,
I posted this very same question in long form in the ZF forum, here is the link ZF thread. I never did get a response. I too would like to know how the shade tree mechanic can accurately make this calculation. When the day comes when I need to do this, if it comes down to it, I'll take the short block assembly and the ZF down to my place of employment and set them up on a surface plate, establish a centerline plane through the output shaft and crank and do the math. I have this terrible feeling that this is an item that has been over looked in many Cleveland rebuilds and could be the culprit in promoting bottom end failures and wear.
So Mark, after you have read the thread I linked to above, does making sure alignment correct seem as critical to you as it does to me?
