Toe explained [url=http://en.wikipedia.org/wiki/Toe_(automotive)]here[/url].
I'm not clear on converting inch of toe to degrees of toe as listed above; it's not a straight fraction to decimal conversion to determine angular measurement. Where inches are the difference between front or leading centerline of treads and how much they are cocked to or away from each other in relation to centerline.
Perhaps one would take radius of tire and preferred toe distance in inches and calculate the angle.
Say for example tire has a 26 inch diameter or 13 inch radius, and preferred toe is 1/8 inch.
Calculate what angle would be for both extremes of toe distance, and preferred.
My 67 gives toe as 3/32†to 5/32†where 1/8†is preferred.
Using this angular calculator for right triangles one can figure out max, min, and preferred angles of toe. I will just calculate preferred angle in this example below:
Enter 1/8 inch as 1 divided by 8 = 0.125†for side (a)
Enter radius of tire from example 13†for side (b)
90 degrees is angle (c) and we are looking for angle (a) the little one.
Three decimal places are more than enough, round angle to two decimal places for the front end guy.

Your front end guy could look at a 76 Dart, or even a newer Aspin for a toe angle. Also a 72 spec is for bias ply tire, not radials, so a later model year would be more useful if you are running radials. Ask how far back his settings go; A body front ends are all the same to 1976 which is about the time when radial tires became standard equipment.
Just my 2 cents:
Lowering front end can open a whole can of worms for alignment setting problems, and handling & ride quality which varies from car to car. All I'm going to say is factory settings (see exception below*) seem to work best over the long haul, its your front end, your tires, and your rear in front seat absorbing any contact with bump stops; do as you please. LOL
* More then stock caster setting is preferred up to the +3 degree range.
Somewhere there is a listing of various front end settings for differing set-ups, stock to full road race settings, in the form of a little chart. I can't find it at the moment, but I'm sure someone will post it for your viewing pleasure.

) because I'm going to be putting long tube headers on it and fully plan on driving it all day everyday this summer and fall. But I am going to need a big time alignment once I tear into the suspension with what I have planned, and this is going to help so much.
