Upgrade MK3s+ to 3.5s upgrade and enclosure and LCD

Finally getting around to doing a bunch of work on my printer.  All the held off service and upgrades being done and came across an issue.  There are no instructions on the xLCD and how to fit it to the outside of the Prusa enclosure.  The instructions for the enclosure have the LCD inside the enclosure which is not good when there is a heater inside where the display would be.  No answer here, I will contact Prusa.

I cannot find instructions on how do disconnect the LCD ribbon cable in any of the Prusa documentation I have downloaded.  I know that there are two side clips on the xLCD.  I want to be able to test my upgrade on the bench before putting it into the enclosure.  I may look at some different ribbon cable connectors for the enclosure and extend them.  

FWIW, I am doing multiple upgrades at this time.  Changing to polymer bearings (as a test), REVO hot end (Long overdue) and finishing the MMU3 upgrade to my hotend.   

I have found that the polymer bearings I purchased don't have the steel shell and can be distorted by tightening the mounting screws.  This affects movement.  I want to try polymer bearings to see how they work for 3D printing.  No lube needed.  Will work to over 100 degrees.  I have already had a bearing seize and damage a 8mm rod, even with lubrication.  I will post more when I get some data.
