I was looking for some a while ago. I found some, but can't remember where at the moment. They were never very specific on model. I lost interest, but it seemed that most used the engine mounting bolts to affix to the bike. Taking this into account, aren't all the motor mounting positions the same for the 750 SOHC? Just a thought!
There are different versions, like the ones listed. Mounting those seems to be a little more ambiguous.
