Those are the ones! That being said, you'll want to look at the top where the shifter attaches. You'll need the one that matches your transmission. One is inside one is out. I think there's a way to re- do the wiring, again bill boost did that write up, but that might only work for the older models. The only exceptions to this are the comp-g and gxp which are specific to those models, though if you have comp-g, I bet you can use regular and just tune the codes out.

The only difference between hd and non is the differential (held on by 4 bolts and a clip).I doubt your stock one is damaged, so you could get one from an n/a and swap the differential making it "hd" if you have a hard time finding good hd ones, plus the n/a ones tend to be driven softer since no supercharger.

Watch out on the gear ratios since some other w- body cars used different gear ratios. If you search the forum on gear ratio it should come up.
