The scan is grainy, so I am having a hard time reading it, but it looks like toe is in degrees and it's negative, which probably means toe-out. The "ranges" are likely for bias ply tires, but I'm not sure if they jibe with original Chevrolet specs. Check the shop manual.
In any event the settings are not very good.
My recommended "touring" settings for radial tires are as follows.
Front: zero camber, as much positive caster as possible up to two degrees, 1/32" toe-in per side.
Rear: negative 0.5 degree camber, 1/32" toe-in per side.
All cross readings should be as close to zero as possible.
The relationship between toe in inches and toe angle in degrees is as follows:
Toe in inches = toe in radians times times tire radius.
2pi radians = 360 degrees
You do the math, and if the alignment guy doesn't understand it find another shop.

Your suggestions for radials are pretty much what I was thinking.
Will see my guy this afternoon.
Thanks to all!
