How did you you that custom dask kit? Did you use the 98 Catera mounting kit? i would rellay like to talk to you more on your installation and what you used and did i have a 98 STS and need a little help
I used a dash kit for a 99 deville, minor mods were needed. The biggest obsticle is modifing the PAC2 module to make the radio work w/factory speakers & amp. Do a search in the infotainment forum if you need more info.
