OK Leon here is the suggested sketch. I don't agree with the bolt-on
motor mount extensions. It will just make this heavy part
heavier and introduce stress concentrations. Make two patterns.
One like this and one with the motor mounts moved in as far as 
you can get them. I would say 14 to 15 inches center to center. 

Leon will move the starter over to the other side.

Here too is a picture of Leon's mate's business that I like to 
call the "Bell Housing Capital of the World". A business like this
could not exist in the states due to our draconian emissions
laws.

I will send you the pertinent dimensions of Tracy's redrive shortly
Leon.
