My boat came with remote controls for my Nissan NS8B. I'm currently replacing the cables because they were getting sticky. Here's what the controls look like (no brand name anywhere that I can find):

Here is the view as I was taking it apart. Notice where the cables come into the control box, where they are supposed to be 'held' there is a little piece of plexiglass or something that is broken, and I need to replace it.

Where would I find a new one and is it even what is supposed to be there??
Here is a better picture. Bottom left, you can see what I'm referring to:

Thanks for any info
