Hi Roscoe,
I mounted mine with three screws through the cowl and the two screws through the console (tranny tunnel), one on each side. I was worried about how securely that would work so I added large fender washers to the back of the cowl screws and the inside of the console. I haven't had any issue with this set-up. I was also thinking that brackets made to come off of the hoop and attech to the face of the dash would work. If you use the right bolt head it would look like the original cars.
