As for your steering box, Straight Line Steering here in California can set you up with a very nice box. They are a small shop, that do excellent quality work and only use US made parts. Not your standard rebuilt steering box from the parts store.
Their website is kinda behind the times, but check them out. Give them a call. I have their box on my ‘74 W200. And one on a ‘73 Ford F-350.
