I didn't get any rack part #'s for Regal, but I assume it wouldn't be likely to have a quick ratio rack. It looks like the better rack available for Cutlass Supreme FE3 is the same as the base model FE1 rack used in Grand Prix. It's pretty simple until 94+ when GM used many different racks for different engines and different years. I focused more detail on GP racks, because they obviously have the more performance-oriented rack selection. I know the TGP has a very quick ratio rack (36-9020) but I wonder how it compares to 36-9021. Also I wonder if any of the newer variable assist racks are quick ratio or not.
