Need Info From Guys That Do Their Own Alignment

For doing caster turn tables are a must.It make taking the measurement so much easier. Need a nice level spot to set up on. I made blocks of 4x4's to mount the turn tables and for the rear wheels to keep the car at the same height on all 4 corners.Also helps for setting toe.A trammel bar(toe bar) can be bought or you can make your own with some conduit,a stationary pointer and a adjustable pointer.Or if working with a helper a tape measure.Crude but gets the job done.Another Item is a scribe to mark the centerline of the front tires.I use chalk on the tires to see the scribe line better.OR you can just use the grooves of the tire.I bought most Items from the Mac tool guy when I was working,he even got me used turn tables.That was back before the internet.Now I'm sure you can fine everything on line.
