Wanted- measurements for Sonora Baby Grand motorboard

[estott]

If anyone has a Sonora Baby Grand, I have a request: could you possibly make me a measured diagram - or better yet a paper tracing - showing the dimensions and where the various bolt holes for the motor are. I'm going to have to modify one for my empty case, or make a new one, and it would save me a lot of grief.

My motorboard opening is about 16 inches square.
