Unless the car is lowered a bunch or raised with hi jackers from the 70's lol this isn't rocket science, get the motor/trans angle and adjust the pinion down or up accordingly to what ever chassis u have to get it to parallel under power. I never worry about the driveshaft and what angle its at

The 78 Service Manual has a section on checking drive angles.
(4A-4) Here is a clip-shot and the angles: (of course the attachment is small on PY)

I wrote these as a development engineer for inclusion in the S truck service manual. Hopefully they are self explanatory.

Thanks Keith for taking the time and effort to post that well written report.
It was my concern over my front working angle being too large that generated my initial post. I will be looking to reduce that angle in the future and any needed change to the rear working angle for better alignment under load in the near future. DV |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
