Alright, here is the write up for mounting my Otterbox phone cradle on my gauge pod.
First, remove the clip from the Otterbox cradle. Basically the disc you see from the phone side has tabs that snap into the clip on the backside. You need to pop those tabs and then it comes apart. It's a bit of a pain, that thing is on there good.
Then remove your gauge pod, and then carefully remove your HD logo insert. Use a hair drier to soften the double sided tape, and then you can use a small screwdriver from the slot in the gauge pod behind it to gently work it off.
This is what it looks like when removed:
And this is what the back side looks like:
Now for hardware and spacers, I raided my stash of R/C stuff and found some nice stainless buttonhead screws and aluminum spacers. These spacers are even threaded the same as the screws, so when installed, a little dab of blue locktite on the spacer threaded will give some extra security.
I had this little chrome insert in my box of misc stuff, and since I didn't want the spacers right on my paint, I used this piece to go between the pod and the spacers. It also doubled nicely as a template.
