Anyone do their own alignments at home?

I am building an altered wheelbase car with a custom suspension and I have my wheels and tires I will be using for the front end. Now I need to get this thing close using shims so I can see if I need to trim the fronts of the fenders or not. What tools do you use for caster/camber/toe? Final alignment will be done at a shop of course.

I think if I can put enough caster in this I will clear the front edge of the fenders without trimming. It has manual rack and pinion if that helps.
