Switched from 16" to 18" rims but can't get alignment?

[AltimusPr1me]

I have an 08 altima coupe 2.5 and recently hit a pot hole or something of that nature and my stock (16 inch) rim broke. I went ahead and got 18 inch rims put on and got tires balanced, however whenever I tried getting them aligned 2 stores said they couldn't align my wheels. first said they didnt have specs bc of aftermarket wheels and second said they couldn't bc my frame may be bent or the bolt/arm is bent but didnt know for sure which one.

What I need to know is should I go ahead and buy a new camber and alignment kit bc i highly doubt my frame bent from a pothole or take to shop and spend 1,000 at least on frame. If I should go ahead and get alignment kit which ones eibach, heard 350z fits, or another kind thanks for any and all help?

I've revised your title to get people's interest (need help is really vague).

If you managed to break a rim, there's a really good chance there's additional damage.
