the two holes are nice for screws, but I was having trouble figuring out a way to get them in there tight with the blast gate in front (how are you supposed to tighten the screw heads? so my solution was to mount the screw in there before anything else, get them tight and painted over the bolts so they won't move. Its kind of hard to tell, but I had to grind away the top of this opening with the dremel so that the lip on the blast gate could fit. Primed this as per usual. I also had to grind away the bottom bit of the lip on the blast gate in order for it to fit.
I melted the mesh cover on the blast gate. Measured and drilled 2 holes.
The gate is easy to access once you have an idea of where it is, its not hard to find if you slightly crouch down.
Inside the vehicle. I am not going to cut the hose until I have a better idea of my interior plans/layout
Looking back it would have been better to have longer screws, that way I would have to do less modification to get that blast gate to fit. On the other hand it would take up more room and stick out more.
