Dana 44 may be bent?

I got a used dana44 rear installed into my tj and when I look at it from a
distance I notice that the tires have negative camber I think it's called...
looks like this: /-\

It looks like its gonna wear my tires unevenly, and I took it to an
alignment shop and the guy said that there's no adjustment for the rear and
to just rotate my tires frequently.

Since there is no adjustment, I'm guessing the tubes are crooked in the
housing? Can they be bent back into shape?

The shop who did the swap was supposed to put in a detroit locker, but for
some reason put in the detroit truetrac. They're gonna fix it Monday, would
they have to take the rear off again to bend it back?
