I've been working on something like this for awhile. They would seem easy to make, but there are a lot of bents and angles in the APillar, and to be vibration resistant and strong, they have to fit like a glove. Also, you can only mount them so low on the APillar due to internal obstructions. I have a set built and running them through a test phase to test strength and durability, as well as visibility and safety. The biggest concern is strength of the APillar after drilling holes. The APillar is pretty weak as it is, and after seeing some after effects of a roll over yesterday, an internal roll cage is a good idea, with or without drilling holes into the APillar. Anyways, here are a few preview pics of my product and don't have a release date or price on them yet. Sorry, I only had one side mounted at the time of the pictures.
