I spoke to the folks at Steer and Gear,, they also did not have info on manual steering box date codes

not sure if this will help. There are a few different ratio of manual steering also, how many turns from lock to lock.

You need to find out if it's big or small pinion spline. I believe Moparts or Big Block Dart has a tech section. I've read you can tell by looking at the top plate
