steering gearbox oil

[Klattu1929]

I am currently rebuilding a 2-tooth steering column/gearbox. The 7-tooth in my car currently I used Penrite semi fluid gearbox lube. For this 2-tooth I am looking at trying the Millers Oils vintage worm steering box oil, sold on Amazon. Has anyone used this or is it not a good product for the 2-tooth gearbox. Planning to do the swap next winter so thought I would get a jump on the Barn opinions. Thanx.
