I'm not planning on mounting a radio in the fairing. What I do need is some storage space. After much pondering I decided to make plates and bolt them where the speakers normally mount. I'll mount some sort of pouch to these plates.
Here are some plates made out of aluminum.
Here they are in place. The four small bolts are 10-24. I ran a tap through the holes to clean them up as the plastic threads weren't in that great of shape.
I bolted these to a small metal plate I put inside the pouches.
This is a camera pouch I found at Walmart. They have several different sizes. The front pocket is big enough to hold my parking puck.
Now I have some (non-locking) storage for keys, etc.
