Hey guys,my 71 Demon needs to be aligned and I was going to bring it down to my auto shop and do it myself to learn about it and all that jazz. Ive never done it before and I understand it can be tricky? Anyone have any advice on how to do it the right way and what specs? It is a stock front end.

These are not all that tricky if they have not been wrecked, and assuming you've brought the bushings and other wear parts up to standard.
There are only three adjustments......caster, camber, which really go together, and toe
You got a service manual? the nombahw WHONE job is to get one. You can download 'em for free:

"The easy trick" on caster. All in the world that camber is, "is" the tilt in or out of the front wheels. You can "do" that with an accurate angle finder / level, buy inexpensive ones, 'er for heck sakes MAKE one
Caster is also simple "once you" learn the trick. All you need do is turn the wheels in 20 degrees and note the camber reading. Then turn the wheels out 20 degrees and note that reading, and subtract the two. That result X 1.5 gives you the caster reading
If you click the link above, you'll see I bought an old Ammco caster / camber gauge. In reality this is a CAMBER gauge, and the second set of numbers works like a slide rule to calculate what I just wrote above
There are many ways to set toe I re-worked a guage that was too large so I can do this alone, see here

"The thing" at the very top of the photo:
is a spring loaded scribe. You either put some tape on the tire tread, or if you can "see" it forgo the tape. Jack the tires up under the a arms and scribe the tires while rotating. This gives you a "true" circle around the axis of the tire
Toe then is quite simply the difference between measured at the rear of the tire and the front. Measure as close as possible to spindle height

The "scoch" chart is what many of us use WITH RADIAL tires. Note that camber is OPPOSITE the factory setting for bias tires. That is, with bias, the old reading had the tires OUT at the top. Modern radials run the tires IN at the top, or "negative" camber
