    Put the shims that were there back where they were.

    Assuming it was aligned close to spec prior to disassembly, it should be close enough to drive it to a pro for proper alignment.

    Every car is different, that's why the shims are used. If you're just getting it close enough to drive short distance to alignment shop info below will get ya there. Make sure you have new top lock nuts to install AFTER the alignment shop is done. I consider them single use fasteners and have seen more than a few cases where old or reused nuts have loosened up and shims fall out then have to spend again for another alignment. Back in the day when these cars were made the alignment shops kept new nuts in stock and replaced them. Now you're lucky if the shop has standard wrenches and actually knows how to do alignments on old cars.

    You can start by putting a couple 1/8" ones in the rear and one in the front to get ya in the ball park. Then drop the car to the floor, bounce it a few times and roll it forward and back a few feet. Then put a level up against the tire vertically and see if the top of the tire tips in a little bit. If it does move on to adjusting the tie rods. If it tips out put another shim in the front, then lower, bounce, roll, recheck.
