DIY Alignment?

You can make one a lot cheaper and just as accurate. Get yourself a digital level and or protractor, nowadays there' s lot's of 'em

The thing is, caster is calculated from camber + tire turn-in / turn out. I have (and use) and old Ammco caster / camber gauge, but the caster part is actually just a slide rule calculator function built into the device
