I'm pretty sure that the rear trailing arms are a direct swap too. Once read here that the Gen2 trailing arms were a bit beefier.

Also read here ages ago that Gen2 coil springs were desired and also a direct swap. In the Gen1's they were said to have provided a little extra lift (about 0.75 to 1.5" lift) without having to install an actual lift kit.
