Hello! (I tried sending you a private message, but I guess my account is too new, didnt seem to work!)
New owner here!
I'm looking to go about the same way you went but with the black top case mount (the non-alum).
What i was worried with is that the mounting hole that the instructions seem to indicate we go through, they indicate we'll use a nut on the inside but from looking at my bike, it has a welded nut there... I didnt purchase the givi bracket yet, but i'm worried that won't work.
Obviously yours did, so I assume this is not a problem. Does the provided bracket slip in between the oem baggage carrier and the frame part?
It's not very easy to explain, but since you've just installed yours, you may know what i'm talking about!
Hopefully you do! I look forward to ordering this part!
