2. Go to Grand Theft Auto V\x64v.rpf\models\cdimages\streamedpeds_players.rpf\player_one\
3. Press Edit Mode button in OpenIV and replace "uppr_diff_004_a_uni.ytd" and "uppr_diff_004_c_uni.ytd" with the files in the .zip
4. Press again Edit Mode to disable it and then you can play the game.

Update: Added "Feeling Lucky" version (black shirt only - yes, because it's better looking :D )
