Hi,
I bought a 1986 Grand Prix to rebuild. It's in pretty good shape but the drive shaft was out of it and the U joints removed. The shaft and yoke weren't marked for alignment when replacing. Is there a way to figure out how it all goes back together so the balance and alignment are correct. Thanks in advance for any help or advice that you can offer.

Unfortunately you can't tell at this point without any markings.
Just install the Universal Joints and the Yoke and see if you have a vibration when it is ready to drive. In most cases you won't have any problems. If you do, then block the tires and apply the emergence brake for safety, put the car in neutral and remove the drive shaft from the rear differential, turn the shaft 180 degrees and install.
Test drive the car and the vibration should change for the better, as long as the shaft or yoke are not bent.
If you need anymore information just let us know, we will be glad to help.

I appreciate the info. Does it matter what position the front yoke is attached to the drive shaft? Thanks again. Great site !!

No just put it together and test drive the car in most cases it should be fine.
