I had a Craven Speed flexpod in my R53 that bolted into the back of my Tach. I loved where it sat, until the attachment bolts stripped out the plastic in the tach and it fell out.

Looking for an non-Tach mounted solution (also possibly an idea on how to fix my Tach...can I tap bigger holes in the plastic mounts?). Ideas?

Note I have a Kuda dashboard mount for my iPhone. I've considered cutting a piece of thick aluminum about 6 inches long and drilling mounting hole locations at each end, attach it to the Kuda dash mount, and attach both the GPA and the iPhone to a single mount. Thoughts?
