Thanks for the good idea on this one!
I'd been looking for a good place to mount my RAM mount from my dirtbike iin my '02 4runner for a while, and saw that this was the perfect location for me.
I did mine little different though. The ram mount RAM-B-367U has a hole in the middle so you can use whatever bolt you need.
Here is what it looks like mounted up:
And with GPS:
With the shorter stem, you don't get as much range of motion but it works perfectly for me. The bonus is that I'm left handed so I can actually use the gps while I'm driving. :smiley_drive:
The only problem I had was the amount of thread lock Toyota used on the damn screw. A 5 minute job turned into an hour and a half when I had to drill the thing out! :smilies27
