[Healeys] Add overdrive

[Rich C]

Mitch,

If you go for a used overdrive gearbox assembly, you have the definite 
advantage of having your own known good gearbox. All the internal gears are 
the same. If you had to, you could use your good parts, do new bearings, 
synchros and seals and the longer o/d input shaft from the o/d box you find, 
and you'd be all set without doing the unthinkable of deviating away from a 
proper Healey gearbox.
