Yes, you are correct about the pinion yoke's centerline and transmission output's centerline needing to be parallel in both planes (when viewed from the top from front to back as well as the side from front to back). Offset and parallel is good. Offset and not parallel is bad. Maybe you're right though dayj1.....it may be very insignificant. I guess I was more curious of the "why" Holley felt it significant enough to mention that 1/16" offset. Maybe I'll call their tech line and try to pick their brains.

I'm admittedly a perfectionist to a fault. I read and read and dwell on making sure stuff is done right to the point of going crazy. But when you put it all in perspective, these trucks definitely weren't built to close tolerances.
