Yes I knew about that. That is strange. I had to make the
casting wider to accommodate that.

BTW I moved the starter down to get a narrower over all
width on the bell housing casting. 

There is a bit of a trick you can do to
simplify the casting. That is; have the starter share the
lower right hand bell housing bolt. In order to do this you
need to rotate the starter CW around its own axis a small amount. 
When you do this the aluminum casting around the starter pinion 
gear could interfere with the ring gear so you may need to 
die grind on it a bit.
