I am referring to the motor mount holes in the intermediate housing. 
 
Hi Wendell,
 
I remembered that I have almost a whole 2nd gen engine in a box in the corner of my garage.  Unfortunately, this box is guarded by black widow spiders (wish I was kidding), so at extreme risk (well not THAT extreme), and to demonstrate the usefulness  of the thread gauge (buy one and maybe I'll get commission), I pulled out the box-o-parts.  All three bolt of the mount holes in the intermediate housing in my box are M12 x 1.5 pitch.  
 
Good luck with your bolt quest :-)
 
Rusty
