I’ve been fiddling with the front end alignment on my 69 GTO. It was too difficult trying to schedule something with a place that knows what they’re doing. I bought a caster/camber gauge with a pretty delicate digital level. Then scoured the internet for info on what numbers work well. I’ve got many hours of trial and error getting to the point where it tracks pretty well. I’ve had fun and learned a lot. I’m not sure the alignment specs are all that critical for a driver. A few degrees of positive caster, about zero camber, and set the toe in 1/16 to 1/8. The racers and auto crossers like to dial it in a certain way and there is a science to that.
