Hello Tim,

If your buddy wants to run a mechanical speedo, then all that is needed is 
to bore out the speedometer drive boss on a '65 car case to make a late '65 
FC style differential.  I have the drawings and a fixture to do this 
operation.  I had the replacement case for our '65 Greenbrier bored at a 
local machine shop (here in the great white Upper Peninsula of MI) but the 
owner has since retired. I am sure Ken Hand could do the same modification 
now that he has a vertical mill.  Ken assembled my differential using a '64 
pinion shaft (with the speedo worm gear) and other internals from a '65 
posi differential.  A couple years ago we advertised that this modification 
could be done, but there were no takers.  I suggest you refer this fellow 
to Ken Hand and let it go from there.
