66 steering box
There is a core plug on the box that could be removed to gain access, but gettiing the old 90 weight gear lube (that has prolly solidified by now) from the box...may necessitate taking it apart.
Unless you had some reason to think your steering box has been contaminated (water, dirt, rust) due to the top plug being missing or such - I wouldn't worry about flushing it. Otherwise, I'd suggest you simply remove the top plug and shoot about 6-8 pumps from your grease gun into the steering box, replace the plug and never look back.......
