I know all about the different springs, and sway bars found in different thirdgen models, but what about other suspension parts like.

Panhard Bars, Torque Arms, A arms, Lower Control arms and crossmembers?

These were the same on all thirdgen for 10 years?

 

Correct. The LCA's and panhard rod where also the same ones found on ever year 4th gen as well. A-arms changed with the generation change but remained the same throughout all 3rd gen's.
