So I'm finally getting around to finishing this mod.
Reviving an old thread because of procrastination.
To refresh, our simple "putting the 2013 sun visor into the 2012 visor mount" didn't go as smoothly as some of us might have liked.
There is a problem because of a design difference involving a taper in the 2012 post that is not present in the 2013 mount, so the post didn't "snap" into the mount as we had hoped.
My plan was to grind the post down so that it was about 1mm shy of the top of the mount to allow for tension, and then jam a 6m sheet metal screw into the hole of the post, add a couple washers, tighten it up, and Bob's your uncle.
The hole is deep enough that I believed I could get plenty of purchase with the screw to apply enough force to maintain the tension.
What I discovered however, as I started to "carefully" grind down the post, was that there is a metal "sleeve" in there that you can see in this picture.
As with just about everything I have done to this car; Time for an on-the-fly change of plans, hopefully for the better.
I went ahead and finished grinding things to the configuration I originally intended, seen in this picture:
I then threaded the sleeve to accept an 10-32 - 3/4" Cheese Head machine screw.
Was going to go with a 5M, but but was a bit too big.
I added 2 #12 SS Flat washers to give the movement something to bear(ing) on instead of the plastic, and finished with a split washer, not to keep the screw from backing out, but as a surrogate spring to keep some tension in the system.
Once I was happy with it, I put some Blue thread locker on the screw and a bit if grease between the washers.
It seems to work well, and it hopefully looks like this was my plan all along.
Once I got it all figured out, the actual time to DO the mod was minimal.
I hope this helps somebody out there.
I'm going to do the other side as well, just because the quality of the visor is so much better, and I didn't lease.
While I am happy with the finished result, If I had it to do over again, I would seriously consider keeping the '13 visor intact, and instead modding the attachment to make it fit as someone else described above.
