Ok, so a while back I converted my '65 from manual to power steering, but my mechanic didn't swap out the steering gearbox. The car is obviously still drivable but it has a lot more "play" than my '73, that came with power steering from the factory. I'm pretty sure that there are some differences between the two (8 year difference in the cars), but there shouldn't be that much of a difference, right? It's getting to a point where it's kind of annoying, so I want to do that swap. I've seen the Flaming River boxes and others, but what's the advantage over the stock boxes? Any tips, suggestions, recommendations, are welcomed.
