   According to my Copper State Bolt & Nut handbook, M12 bolts come
in two threads: coarse - 1.75 and fine - 1.5.  I'd send you to their web
site, but it appears they are redesigning it. 
 
Hi Dale,
 
Maybe they're redesigning the page to include the 1.25 pitch :-)  
 
McMaster sells M12 in 1.25, 1.5, and 1.75 pitches.  The real problem seems to be deciding what the correct size is.  
 
Wendell,  Just to be sure, are you talking about a motor mount hole in the 2nd gen intermediate housing, or the 3rd gen rear housing?  
 
Rusty  
I am referring to the motor mount holes in the intermediate housing.
I thought you had supplied all the bolt sizes in the past but as of yet, have not found it on my computer.
Wendell
