radio interchange question

I just installed the thumb wheel version of the Redondo and got it all functional. Its a nice piece once you get everything mounted correctly to fit your car. The face plate and knobs/thumb wheels are separate of the main deck and can be positioned in different locations and are connected with harnesses. So fitting the deck can be time consuming and I had to trim some of the bracket to fit the opening. The direction clearly state to modify the bracket as needed to fit (i.e. bend, cut, swear, drink beer, swear some more, drink more beer, add your own parts, etc), so this isn't a 100% drop in right our of the box. Mounting isn't stock either, I had to buy longer 1/4-20 counter sunk bolts, nut and washers to mount mine from behind the dash frame and they include a strap to mount the rear of the unit to support it. Don't count on the two posts to support the deck like the original or other aftermarket 2 post decks.
