The '92 is kind of in a ball park of it's own when it comes to the front suspension parts. Some of the parts interchange with earlier years, some with the later years.
I'm pretty sure EPI makes a "kit" to replace bushings for the A arms

 

You can get some hard round stock cut it to the right length and cut threads on it.
