This seemed like a very good soloution to the problem of having to remove and reinstall the long 12mm bolts each time you drop the skid plate so I gave it a try.
After a couple of trys local supplier managed to find 12mm x 1.25 x 80 mm grade #10, fully threaded bolts , along with some nuts and washers. They had nothing available that was plated for corrosion.
Which soon became 67mm long studs which is what was needed for my install with the Givi engine guards.
Sorry to drag this back to the top but I have a question. I did this mod last weekend. Both bolts were pretty close to 67mm...less than a mm difference. However when I installed them the left stud sticks out about 1/4" more than the right. I am pretty sure I threaded them in all the way and backed it out a turn. Marked the bolts with a sharpie to make sure they didn't turn when I tightened them. Is it possible one hole is deeper than the other?? After the ride this weekend I'm going to take it off and check it again.
Double nut and tighten them into the block
Washer and nut equal the same thickness as the ACD supplied spacer and can be tightened down and not needed to be removed for skidplate removal.
A couple of washers and nylock nuts and done. Should make the skidplate re and re a little easier when it comes time for the oil change.
