Not that set up but very similar set up. I put it together piece meal from Amazon mostly but I think I got the bracket off eBay. I have just at $80 in the whole set up.
The only thing jumps out at me different is my mounting bracket is the passenger side one and mine is Black.
I think you probably might want the 4 foot. This picture shows my 4 foot Firestick but unfortunately cuts off the top. It is not that much more out of picture. Taller is almost always better with these things. (forgive the use of the Grey cable... I got a Black one to use but didn't have it yet when I took these pictures)
