Gilrock:
Probably be safer to buy one of those SD card extension cables for around $7

You are probably right. Shopping now. :)

Thanks to Gilrocks suggestion, I have moved the SDCard position to a more accessible place.

Ordered a extender adapter from amazon. It was around 10 bucks, but was shipped from within US, not China, so it arrived in 3 days.
(Im sure it was made in China, but thats way to common these days.)

I folded the cable and tapped it down as flat as I could.

The adapter came with some double sided tape. I tapped it down to back of monitor. Its a little whoppy-jawed (crooked), but the tape sticks like crazy, guess I can live with it.

I then placed the monitor circuit board back on top of it, and replaced the plexi chassis.

I like this a lot more, but it's a shame I had to do that to start with.

Here is the code for the encoder to control volume.
I still need to get current volume setting when starting. (I cant seem to find the command for this).
I got the code from the credited website, but had to modify it quite a bit for my use.

--- Code: ---#!/usr/bin/env python3

# set master volume with encoder for rpi. KRR 05/10/2021

# adapted to suit my needs from https://github.com/bruceiow/rPiVolumeControl/blob/master/VolumeControl.py

from RPi import GPIO
from time import sleep
import subprocess
from subprocess import call

# These are the GPIO numbers for the clk,dt and mute switch pins from the encoder
clk =35
dt = 37
mute_pin=11

GPIO.setmode(GPIO.BOARD)
GPIO.setup(clk, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(dt, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(mute_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

counter = 50 # need to get current volume setting from amixer
oldcounter=counter
clkLastState = not GPIO.input(clk) # using NOT because Im using GND for switch commons
mute=False

def switch_mute(channel):
global mute
if mute:
mute=False
call (["amixer","set", "Master","unmute"])
else:
mute=True
call (["amixer","set", "Master","mute"])

GPIO.add_event_detect(mute_pin, GPIO.FALLING, callback=switch_mute, bouncetime=100)

try:
while True:
if not mute:
clkState = not GPIO.input(clk)
dtState = not GPIO.input(dt)
if clkState != clkLastState:
clkLastState = clkState
if dtState != clkState:
if counter <101:
counter += 1
else:
if counter >1:
counter -= 1
#if counter<1:counter=1
#if counter>100: counter=100

if counter!= oldcounter:
call (["amixer","sset", "Master",str(counter)+"%"])
oldcounter=counter
#sleep(0.1) # may need to adjust
finally:
GPIO.cleanup()

--- End code ---

Bad news from the front:
The SD Card crapped out. Kept getting "input/output error". Lost everything on the card.
Reformatted card and re-installed everything (I had backups on my pc). Still got the errors.
I removed the extension cable adapter, installed card directly into RPi. Still got the errors.
Im thinking that card is toast.
I formatted another card, installed OS (Debian Buster) image, then spent a good part of the day re-installing software and scripts.
So far so good.
Im afraid now to use that extension adapter, what if that is what crapped on my first sdcard?
