I completely disagree with GGreen. Look, Jemtromno, you need to find your DS Library folder. To do that, open DS, press F2 or Edit => Preferences in
the top menu to open Preferences. Select the content tab and press the wide button at the bottom marked Content Directory Manager. That will show you the location of your DS library. Close DS. Copy the Data, Props and Runtime directories from your Prohibition Car Bundle. Go to your DS library directory, open it and paste the 3 copied directories into your DS library. Open DS. The user-facing files will be in the Props folder of DS as DocPhoton shows above.
