I'm curious about the Volare specs as well. The suspensions on the Volare are different from the 62-72 B body.
Radial tire spec's are a little different from Bias ply tires. The guys doing alignments today may be too young to understand the difference and simply refer to the computer or the book. Not good.
I like my cars to handle well, but in the case of a stock type cruiser, you'll do fine with the following settings:
Camber: 0 degrees
Caster: 2 degrees POS.
Toe: 1/16" IN
Manual steering cars often have ZERO degrees of Caster to help the car steer easier. Radial tires will allow you to run more Caster.
I'd look into independent shops rather than large "chain" tire/alignment shops. With the "indies" you may have a better chance of finding an old timer than remembers these cars and knows how to work on them.
