AOB and ADZ - is there a difference?

[Robert B.]

Hello Again:

Those ADZs are gone, but I can get 36 units of AOB. According to my
version of FA, these 2 trannies are identical except for the rear tail
housing. We compared them both and only see one hole in the ADZ (used
for a timing light) that is not there on the AOB. FA shows the
bellhousing as having the same number. We couldn't see any difference in
the tail housings at all.

Keith at Anderson Motorsport told me that the ADZ has a final drive
ratio of 3.89 and that FA is wrong. I believe that the AOB can be used
instead of the ADZ, since there are probably a lot of people wanting one
of those new, but old stock ADZ. If the AOB works, I can get 36 of them
for less than $900 each...

Kind Regards

Rob
