Doh!
I found that putting a vertical plug-in into the left most slot so I
could reach the adjustments on the right side was not effective but
maybe you can manage it.
I cut one of my tuning tools in half and shortened it so I could reach
the TCXO frequency adjustment inside my HP 5315A because a longer tool
would not fit at all.

I have a R7704 rack mounted unit - the CRT is on the left. But your note gave me an idea - perhaps I can put the 7A18 in the right vertical slot, leave the left empty and see if I can get a small screw driver to fit in the empty slot. Will try that tomorrow.

If you remove the left cover panel on your 7000 mainframe, you can
reach most if not all of the 7A18 calibration adjustments.

Thanks to everyone who responded - I was able to clean the 2 contacts for the 10X attenuation and the deflection now works fine. I put a few drops of isopropyl alcohol on the contacts with a small dropper and moved the knob back and forth 15 or 20 times. Never actually touched the contacts with anything per notes below.
So now that the gain is right, I have to adjust the compensation caps for which I need an extender. The one on eBay is far out of my reach financially. How do you guys set the comp caps without an extender card or extension cable?
Again, thanks for your assistance with the deflection contact points.
