Making a fusion stereo fit in my Speedster

[rsandoz]

Anyone have any advice on making a Fusion stereo fit in my Speedster?

Fusion Stereo:

Speedster radio cover:

As you can see, the Sea-Doo radio faceplate has a waterproof cover, which, gets in the way of the waterproof cover built on to the Fusion stereo.

Does anyone make an adapter?

FYI,
I am in the process of attempting to hack this myself.

I ordered a custom cut of ABS sheet plastic from tapplastics 9-3/8" x 4-1/4" (1/4" thick)
