GM lists different part numbers for the different suspension RPO codes (FE2, FE4, F41, etc) and different years. Are there any actual differences between them physically?

Saying I was to pull a lower A-arm out of a 98-02 V6 or V8 F-body and try to bolt it onto a 93-97 engine cradle, would I have issues?

I could be wrong, but I think the a-arms are dimensionally the same, but the difference might be in reference to the hardness of the rubber used in the bushings. FE2, F41, etc, were the option codes for the different suspension performance levels.

That was my thought, but I wanted to be sure before I go pull one off another car. I was planning on replacing the ball joints, but I might go ahead and do the A-arm bushings while I'm at it.

FE2 relates to the ratio of the steering racks, there were two, one that did 2.25 turns lock to lock, and one that did 2.75 turns, l t l. A arms should be the same, even from v6 to v8 models.
