fieldchmn,
I have one installed on my "A" pillar.
Installer must be someone experienced, the pillar has a lot of electronics wiring and air bag, inside of it. Believe they took my passenger side "A" pillar apart to see exactly where they could place it. Picture of it on Thread "On the Road Again"
It can be done.
It is discussed in other Threads, also. Type in driver's grab handle in SEARCH box, above right.
