A reasonable way to do alignment is to get a toe measurement tool. I bought mine from speedway motors I think. It is a way to measure from one side of the car to the other under the car. It has rigid pointers that come upward from square aluminum tubing. You can adjust the zero point and then measure relative toe from the front of the tire to the back.
Add a bubble style camper, caster, inclination gauge. Several to choose from. Longacre, or speedway motors. My guess is $120 or so for the camber guage and $60 or so for the toe guage. Both can give accurate readings on a flat floor. Turn plates help but are not necessary.
I don't think the (stupid) pointer tools that go on the front of the tire are useable.
