Hello JR and all,

All FC's (as well as 60-64 cars) had the speedometer driven from a worm 
gear on the pinion shaft in the differential.  A drive adapter with a spur 
gear fits into a machined hole in the side of the differential case so that 
it meshes with the worm.  The cable attaches with a threaded coupling to 
the drive adapter.  The spur gears were available with different numbers of 
teeth to adjust for different ring & pinion ratios and tire sizes.

The '65 Greenbrier was unique with a '65 car style differential case that 
was bored for the speedometer drive.  I know this subject intimately 
because the differential failed on our '65 Greenbrier (#1000) on the way 
home from Lexington. (Two ring gear bolts broke off and wandered around 
through the gears and cracked the case)  With the help of Ken Hand, I was 
able to modify a spare '65 car case to take the speedometer drive 
adapter.  Last week I finally had the newly rebuilt differential installed 
and our Greenbrier back on the road.

I have kept the fixtures and tooling needed to modify a '65 or later 
differential case for the speedometer drive.  If anyone is interested in 
this modification please contact me or Ken Hand at Handy Car Care (248) 
613-8586.
