I replaced my 2018 gt PP1 center gauge pack with a set from a gt350 gauge pack. The swap for me was a simple plug and play. I dont know if it would be for other models. I am now selling my stock PP1 gauge pack as well as the other gt350 trim, the difference is the gt350 is black chrome instead of bright chrome. Message me if you are interested it the package.

 

Looks stock but gives me the oil temp right next to the oil pressure. The Shelby did a great job with the stock set up, and now I have it on mine.

 

Looks great!
