flush mount controls

[tuckerboy]

I am building a new boat and dont want to use the conventional sidemount controls and cant use the binnacle mount so would like to use the flush mount but the problem I am having is that I cannot find dimensions for the unit to see if it will fit in the space I have. The only thing I can find online is a picture of the part of the unit that you see after it is installed, nothing of the guts that is hidden. Any idea where I can find the dimensions. I am sure they must exist in some form or other. The boat is just too pretty to use the conventional unit IMHO Thanks for any help.
