Anyone know where i can get the thing that converts a double din to a single din for my hawkeye.

 

Buy a Legacy Silver Single Din Tray off of a breaker or ebay.
You can mount that in the bottom or top slot of the mounting plates, leaving you wit ha single din opening, like this:

It just needs a couple of holes drilling and a couple of short self tapping plastic screws to fit. Takes 30 mins.
