Andrew, You're right in that it seems the discussion always centers around pinion angle rather than lateral alignment. I'm assuming that you're rear end is mounted 90 degrees to the chassis center line even if it is offset a little (otherwise it would "crab"). If I'm thinking about this right then you would want the center line of your engine/transmission to also be parrallel with the centerline of your chassis in that same plane. I expect that's a little harder to measure than pinion angle at least with the body on. I guess you could use plumb bobs on the center of the balancer and tailshaft and mark it out on the garage floor. It will be interesting to see how you solve this one.
