The OD driveshaft is 2 inches longer than the non OD, and the rear trannie
support has to move 2 inches forward. The non OD driveshaft WILL NOT stretch
for an OD.

Off the top of my head:
1) An overdrive needs the output shaft from the transmission to
match. Non-overdrives have a relatively long output shaft. The OD
units just have a stub that splines into the OD unit.
2) I assume you know that the overdrives from 4-synchro trannys
is different than 3-synchro trannies and you need to have the
right one. Parts catalogs have the correct names (Vicki B).
3) There is some controversy as to whether the driveshaft will fit.
In any case it is fractions of an inch different. The pragmatists
say it don't matter and the purists swear there is an important
difference. If I remember right, the OD driveshaft has a different
stock number and is fractionally longer than normal dirveshaft.
