[Installation] 

Use OpenIV to make these changes. 

___ADD-ON___ 
  
  1. Add new line: 
  <Item>dlcpacks:\mustangmach1\</Item>
  to file .\update\update.rpf\common\data\dlclist.xml 
  So it ends like this:
      <Item>dlcpacks:\mustangmach1\</Item>
    </Paths>	
  </SMandatoryPacksData>

  2. Copy the mustangmach1 folder into the dlcpacks folder so it looks like this: 
  .\update\x64\dlcpacks\mustangmach1\dlc.rpf

  3. Spawn carname using a trainer: mustangmach1

___REPLACE___ 

  1. Replace the 3 STALION files and delete stalion+hi.ytd in the following RPF:
      .\x64w.rpf\dlcpacks\spupgrade\dlc.rpf\x64\levels\gta5\vehicles\upgradevehicles.rpf
      (you might need to replace the ytd here too: .\update\x64\dlcpacks\patchday1ng\dlc.rpf\x64\txd_patches.rpf)

  2 Open the handling file and replace the STALION section:
      .\Grand Theft Auto V\update\update.rpf\common\data\handling.meta
      Search for the STALION section and replace it with the content from the included "handling section.txt"

  3 Open the vehicles file and replace the STALION section:
      .\Grand Theft Auto V\x64w.rpf\dlcpacks\spupgrade\dlc.rpf\common\data\levels\gta5\vehicles.meta
      Search for the STALION section and replace it with the contect (BOTH PARTS!) from the included "vehicles sections.txt"

  Note: Replace does not include the bodymods.


Enjoy!!
