1999 Mitsubishi Eclipse strut tower (area)

Suspension problem
1999 Mitsubishi Eclipse 4 cyl All Wheel Drive Manual 121XXX miles

so i have a 99' mitsubishi eclipse GSX

the problem i am having is i had the transmission replaced (brand new) got control arms put in as well.
but the mechanics noticed i had rubbing on my inner right tire.
they looked at my strut tower (housing) i believe where the strut slides up and bolts in. well ok, when u look inside my engine bay and you locate the struts tower housing left and right side, the right one looks like it had (fiberglassed repair or like rewelded) i dont see any cutting inside the engine bay, but i may think it had been in an accident.
and my alignment keeps getting out of line making my steering pull i believe to the right. and i dont know how they will fix this problem since it may be like part of the chassi itself, can you please give me advice or a possible solution of how they may fix this, if it is with cutting and rewelding or whatever. im in dire need of help.
