Are you referring to the metal plate on the face of steering column controls (turn signal stalks, etc)?
If so, those controls are adjustable fore/aft on the steering column. There is a screw and clamp on the bottom side of the steering. There is also a hole (slot) in the bottom cover (shown above) which allows access to the screw.
If you're referring to something else, apologies but perhaps a pic would be more clear to describe the issue.

This may have been posted but rubbing of Momo hub against the turn signal switch housing can be adjusted by releasing the clamp holding the switch assembly to the steering column and repositioning it.

Follow up to my previous post, as I decided to take the time to put together a detailed guide on this. There are (were) a total of (8) different bottom clamshells for the 964 (two of which are NLA).
Firstly, there are two different styles of 964 clamshells. There is the one that has large radius, "rounded" corners. Then there is the "square" corner version (this is the one which appeared on the 993 RS).
For each of those styles, there are (4) different bottom versions that were available (a few are no longer available). The four variations of each style are: "without CC or OBC", "with CC", "with OBC", with CC and OBC"
"Squared corners" 964 bottom clamshells (as equipped on 993 RS):
964-552-275-00-01C - without cruise control; without on-board computer
964-552-275-01-01C - with cruise control; without ob-board computer
964-552-275-04-01C. - without cruise control; with on-board computer
964-552-275-05-01C - with cruise control; with on-board computer
Note: 964-552-273-00-01C is the corresponding top clamshell piece for the "square" style

I took the assembly apart and checked for voltage in the brown wire with the white stripe that connects to pin 71 in the connector. With the ignition on and off, there is no detectable voltage on the wire. Checked the fuse #3, looks fine.
Any idea what kind of voltage I should be seeing on the wire?
Never mind, I resolved it. I figured out I needed to turn the ignition on to activate the horn after the car sits for a while. All good!

It can get daunting sorting those out via the PET or people referencing the ones they ordered, which may not be compatible with everyone's options.
Figured I'd break it down into the two styles and then clearly list the options with some color coding for ease of reading.

This is a fantastic post, thank you all. for your continued input - I think I got information overload! Anyone in the LA area done this before and want to give me a hand? Beer will be provided

What is the trick for getting the leather center pad that has the horn button onto the RS wheel? I can get the top notched in but then the bottom parts refuse to latch around the metal spokes of the steering wheel.

It's a pain to get on properly. Starting with the top is correct, then as you pull down you have to work the bottoms of the side spokes on then finally the bottom side sections. I used a plastic pry tool to open it a bit while I was working it on but BE CAREFUL doing that.
