Ya, obviously we can't afford what our shops had - nor would you want to for home use. I like my magnetic "Deco" caster / camber gauge, but it has some short comings - which perpetrated this thread. My turn tables are "Rand" units that I bought on E-bag. Heavy duty quality ball bearing units for a great price. There are more toe gauges out there than you and I have toes. A good quality tape measure can fill most of the other bills. It's time consuming work to do it at home, but at least you know it's right, and you can play with settings all you want. I know for a fact that my street rod diff is off side to side about 3/8". Not gonna worry about it for that amount, as I would have to relocate all 4 link perches on the housing to correct it. Set back is on the $. I started out with 3* of caster and I didn't like the poor wheel return on corners. Upped it to 6* and the wheel returns real nice with no noticeable increase in steering effort. All stuff you can do without a major tool investment.
