I just drove my '66 with the 3/4" caster mod from SC to OH and back this weekend, 1100 miles round trip. Even with the worn out stock manual steering box it tracked dead straight and required minimal effort to keep the truck in the middle of my lane, even on the rough and narrow two lane highways through Virginia. Parking isn't fun, but the tradeoff once you're rolling is worth it. I'm looking into a Borgeson power box for it once I find 250 pump brackets.
