Chartplotter nacelle for top of dash installation?
 

I am installing a Lowrance HDS7m chartplotter on the top of the dash in a 2007 35 Lightning. Does anyone make a sloped box that fits the dashtop contours that would allow flush mounting the chartplotter or other electronics? Trying to avoid the open bracket and wires showing.

Not that I have found, in the process of making one for my boat right now.
