advise for suspension setup for 67 dart

I guess my big issue was I had no idea what to tell the alignment shop when I got it done. I can understand that the tire technology and style has a lot to do with how the car reacts and what sort of settings it likes. I can't really blame the shop for using stock specs since that's what they have available when they look it up as far as I know, but next time I go in I figured I might try to get it done a little differently to see if it made it handle a little better. I need to check the sheet they gave me anyway. For all I know they may have updated specs to go with newer tires.
