Indicator fitment

Good morning all, a couple of quick questions regarding the fitting of indicators

My 250 superdream didn't have any indicators fitted on it when I bought it, so, I have seen various places and prices of where I can get them from

Now, my question is, I have seen that there are actual fittings for them, as seen in the pic below 



I understand that the black plastic part will fit either side, but, is it top side on one side and bottom side on the other? YES

Or both on top, but facing opposite directions 

And, how do the front indicators fit?



An M6 Flange Bolt goes through the indicator hole and screws into the Headlamp mounting ears on the dedicated brackets - There is a small spacer as seen above, diameter sized to fit through the indicator hole

I have not seen the fittings for them

Also, does anyone know the actual size and type of screw that secures the right bar switch gear in place? One is M5X35mm and one M5x25mm Both Pan Head - I have used Hex Heads and a washer on mine much easier to manage

Any help will be greatly appreciated
