Give me the best way to measure front end, rear end, crossover whatever to get the best idea if I have the car square. I just reworked the rear axle with radius rods and coil over shocks. Now I want to make sure the rear end is straight with the front end etc. Of course I bought this car and don't even know if the frame is square itself but I want to be able to get it as close as possible. Oh, also pinion angle.
