So....this is my first published skin here. Please be gracious. 
The Joe Crevier BMW M1 PROCAR 1981 IMSA skin, raced by Al Unser Jr. and Jo Crevier in 1981.
Probably not super exact everywhere but I'll hope it will work for you.
HOW TO USE
Please copy the bottom section into your personal "bmw_m1_procar.xml" file you created.
<LIVERY_OVERRIDE LIVERY="23" NAME="Crevier #67" BASELIVERY="SilverWheels">
<PREVIEWIMAGE PATH="FB\M1_CrevierP.dds" />
<TEXTURE NAME="BODY" PATH="FB\M1_Crevier.dds" />
<TEXTURE NAME="WINDSCREEN" PATH="FB\M1_CrevierB.dds" />
</LIVERY_OVERRIDE> -->
</USER_OVERRIDES>
The path is like the following: Steam\steamapps\common\Automobilista 2\Vehicles\Textures\CustomLiveries\Overrides\bmw_m1_procar.xml
Remember: FB is just the name of my folder, yours might be different so you have to rename FB to yours (also in copied text).
