I guess I'm just too accustomed to doing it right the first time. Changing camber with a couple of big chains, a piece of I-beam, and a 20-ton bottle jack was routine around all the shops where I've worked, and caster shims were always kept in stock. Most of those shops (including one school shop) still had the twist fixtures for adjusting caster on one side only.
