Strut Rod Question

I see that Firm Feel sells adjustable strut rods, with the explanation that they are necessary to properly align the front end when thicker rod bushings are used.

Long ago (well, several years ago) I put in new Poly Mopar rod bushings, and they were definitely thicker than stock. So thick that I was unable to reinstall the cotter key in front of the nut on the K-member end.

If this is the case, should I be looking at these adjustable rods? Are the thicker bushings pushing my LCAs out of alignment?
