WG 19K4906 monitor: on what side should it rest for vertical games ?

[Mamezilla]

I'm a complete a noob in regard of arcade monitors.  I've looked around and haven't found the answer.  I want to install a WG 19k4906 monitor in an old beaten up Space Duel cabinet I have had laying around for a couple of years.  This cabinet will be only for vertical classics.  On what side should the monitor be rested so that the image isn't upside down ? 

I'm currently repairing the wood on the cabinet and want to install the mounting rack of the monitor at the same time, but it seems the metal support of the monitor has a piece on each side that prevents installing it on it's side (see picture below).    Can I remove this part of the metal chassis ?

PS:  Hopefully I'm clear enough since english is not my native language

Typically you would rotate the monitor to the left from the position you have it sitting in the picture.
But that's not always true.
Either way would work because you could flip the yoke harness to correct the orientation if it turns out upside down.

judt to be sure and illimanate playing/switching yokes, just plug in your GAME and fire it up. YOu should see how your Vertical GAME on the screen. If it's for MAME it does not matter cause you have  -ROR & -ROL options.

Thanks guys for your replies.  I'm asking these questions because I'll probably have to modify the wooden shelf on which the monitor will rest to accomodate the metal part on it's side (cut a slot on the shelf so that that metal part goes in).  If I remove that metal part, I'd have to remove completely the metal side and I'm afraid the monitor would be less solid in the end since a part of the frame would be missing.

Also since the monitor isn't installed yet, I'm thinking about doing or having a new cap kit done in it before I do.  I asked the questions because the monitor hasn't been plugged since I bought it 4 years ago.  I have soldering skills but since it involves high voltage and I'm afraid to put any scewdriver to discharge it, I don't want to plug it before I end up doing some soldering in it.

Sorry for my english since it isn't my native language.
