I will  soon (or likely later) install a '66 4-speed into my '65 Monza 140.  
I  read in "How to Keep Your Corvair Alive" there is a need to grind relief in 
 the differential flange face.  Does anyone have images they could forward  
to me?  I have not had this apart so it's all new to me.  Also, are  there any 
modifications to the transmission that are recommended when I have  it rebuilt 
(i.e. change gears for close ratio, anything, etc.)?  Any  other advise is 
welcomed.

You might not want to hear it, but I suggest you keep looking for a 66  
differential to use with the 66 4-speed. Chevy decided that you need 6 bolts - I  
would go with that. If you can find a bad one, broken spider gears? (Check your 
 local V8 Corvair guy!) you could move almost everything into that case. You  
might still need a little clearance, the pinion shaft on the 65 diff is  
supposedly longer - by a little bit - than the 66. Supposedly it is so close  that 
it only affects some cars. Ask, don't assume. - Seth  Emerson
