Hi
very interesting but nobody understands where you drilled the whole exactly, what solenoid you are talking about
so, please explain everything in details as it looks interesting
and would be also interesting to tell us your source, or is this just a guess

Just did it too
super easy mod if you are not in a rush
careful, watch little filters (red circles), they might fall out
don't forget to drop them back in the two solenoid holes, those with colored tops, before you put those back

the hole to drill to 4.0MM is pointed with the yellow pen

No worries with bolts, all the same size

good luck

you mean the little plastic *****

Yes but I learned int the past, when I was 25 I killed a plate with that mistake. all the ***** fall out and more
but there is a very simple trick
instead of lifting the plate up like a barbarian, you slide it of slowly
