4K vs 2H

[drew <drew@dyermaker.cs.uoguelph.ca>]

Well, I guess you can chalk my 4Ks (I've got quite a few) and 7A's (which
use the same final drive) up to grey area.  They definitely have a 3.94
final drive.

ETKA tells us the 2H used 020 409 143 N (63/16=3.9375) while the 4K and 7A
used 020 409 143 Q (67/17=3.9412)

By contrast, the FN used the 020 409 143 F (74/19=3.8947.)

I surprised by your statement, as evidence suggests that in 84 VW moved
away from the 3.89 final drive (by dropping the FN economy transmission)
in favour of the 3.94 final drive (used in the 4+e 7A.)

The big difference between the 2H and the 4K is the .91 fifth in the 2H vs
the .89 fifth in the 4K, and of course, that the 2H uses the old style
case that cannot be used in an A2.
