67 Barracuda front brake drums, Alignments and tires

Something is not right, mine will cruise all day at 75 mph to 80 mph smooth as glass. Alignment? tires?

Mine too. Do you know where everything was set on the alignment? (meaning what the final Camber, Caster, and Toe were set to) If they set it to factory specs, it was for bias ply tires and may explain how it's handling. What exactly are you fighting? Does it pull, wander, or what?
