Here you go,directly from the 1966 Comet,Falcon,Fairlane and Mustang shop manual.

For Mustangs with V-8 engines:

Caster: -1 to +1 degrees, ideal is 0 degrees
Camber: -1/4 to +1 1/4 degrees, ideal is +1/2 degree
Toe in: 1/8 inch to 3/8 inch, ideal is 1/4 inch

I set mine at different settings than those recommended.

Caster +2 degrees
Camber 0 degrees
Toe in 1/16 to 1/8 inch

Those settings work well for me.
