I reupload the package made by Smonk because the original files dont't work with new versions. I extract the textures to you import into your game using my tool: Texture Pack Importer:
ORIGINAL MOD: http://www.racedepartment.com/downloads/my-winter-car.13166/
In this way, the package works in any version.
Thanks to Smonk for the mod. Is Amazing.

3 Run the Texture Pack Tool.
