Will a bushing change upset my alignment?

Yes.

I just want to argue with Damon, so I will say no......... J/K

It depends on what you are replacing, what you are installing, and how worn out worn out the old parts were. So the real answer is maybe :)

You need to give more specific information to get a good answer.

If you do anything to the lower control arms on an FD you need to get a new alignment as the eccentric bolts there are what adjust camber.

Only things you can safely install without an alignment are the upper arms front and rear, the trailing arms and the STOCK toe links if you don't mix up the left and right sides. Even then it's a good idea to at least have it checked afterwards.
