Thus the problem. The lever either swings opposite to the way the other
drive lever swings and they hit each other, or you mount the drive upside
down.

And in fact the hole size was fine, what I said was "the rails were cut so
far off". TEAC did not make the rails, they were obviously purchased by
PC Limited (and added value?). Let me add that I was very satisfied with my
two TEAC drives when I owned a PC. Furthermore, I am sure that there is a
model of 55's that is the right color/chirality for an AT. I just think that
the ability to determine the proper combination is beyond most retailers.
Purchasers of add in drives for AT's and clones should be aware of these
two potential problems.
