Adjusting A '53 F-1 Box

[TomT/Williamsburg]

I have a little play in my F-1 box in my 32 so I thought I'd try to adjust it some.

So - I know it's the side bolt - I was told that there's a cover and then a bolt underneath to adjust it - does the cover pop off or does it turn off?

Once off, do I turn right to tighten, left to loosen as normal?

Thanks ....
