I've had my steering box in and out several times over the past year. I rebuilt it with a new DWR worm and there were issues - another story.
Things that worked for me & comments:
--Make careful note of position of steering column sealing plates - they're asymmetrical and it's possible to get them installed incorrectly. My car had different sets of holes from previously so the exact position of the engine compartment plate was confusing. When the engine compartment plate is correct the column aligns correctly with the hole in the dash. The engine compartment plate cannot be rotated with the column installed.

--Ditto the bolt position of the rear steering column aluminum split-clamp just forward of the dash.
--I bolted my box with the bolt heads outward toward the fender well. This makes it possible to remove the box in the future without removing the radiator.
--I got tired of dealing with the trafficator wire bullets going through the stator tube. I cut the wires about a foot downstream from the bullets, tinned the ends and installed an intermediate Molex connector. Now removing the trafficator is trivial.
--I refitted my air deflectors with U-nuts at the top points and at the bottom crossbar in order to make installation easier.
--Like to clean up the grille shroud captive nuts with a notched 1/4-28 bolt as a cleanup tap - makes it easier to run these in by hand on re-installation of grille.
