I'm not so sure about the motor being too far back...from the pic in hahnmgh63's post, there is an angle in that bracket which looks about the same as the OP's offset to match. We'll see once the bracket is located though and if it fits or not.

Really enjoying the thread, keep up the good work!

Thanks to a strong business year and generous family, holiday bonus and gifts have fully funded my garage expansion...architect and contractors are working on it now...I'll be sooo much more inclined to pull off a project like this once I have more than a skinny single garage!
