Great job !
I'm about to do the same by fixing my initial RamMount system.
Below the way I follow :

The screws had the good idea to be well away...

The original set of handlebars RamMount system

Which corresponds with the holes of the motorcycle ... but I will have to chamfer the ends..

Like this...

...

Drill half round 12 mm diameter in the front cover of the handlebars ...

Replacing the original bolt by 20 mm. 6 X 20 mm diameter

Support in place ..

Drill half round 12 mm diameter in the back cover of the handlebars ...

Here it is..
