MK4s nextruder Cover change to MK4 cover without the ring?

Can I change my nextruder cover from my MK 4S to the cover from the MK4 because I don’t have the ring that you can see in the first picture. The second picture shows in black, the original cover and in clear the printed cover. I got the print file from Prusa for the MK4s.

There's no pictures.  But you need the ring that's inside the cap. It's a spacer/ thrust bearing.  It's made from a very slippery plastic.

The. MK4s PG-case or cover on my upgrade had no place to install the ring.  The upgrade instructions don’t mention needing the ring.  I. Used the new cover with no ring and have not had any problems.   I checked the old cover and it appears the ring never made contact with the gears.  The new cover has a small relief for the gears from what I remember.  That may be all it needs.  

I have also upgraded for the MMU3 and the Oring that was added to the main-plate tends to hold the gears from moving front to back. 

I see no problem with the old cover except it wont say MK4S.

The STL files for the Nextruder clearly have a space for the ring.  I stand by that a 3d printed cover needs the ring.

I think the injection molded cover you get with the upgrade kit doesn't need it, but a 3d printed version does.
