well, obviously, if you used a 67.5, you'd be destroying classics, whereas the
68 was relatively plentiful!!!
(heh heh)
Biggest RACING reason I can think is that the 67.5 has a removable windshield,
and thus can (has to) run as an open car, whereas the 68's is fixed. In some
rules classifications, that lets you put a hardtop on it and run as a closed
car.
Thus, an aerodynamic advantage/disadvantage....
fwiw,
