SunExpress Boeing 737-800 "SGE-Epress Eintracht Frankfurt" Livery

Since this is a livery, you'll need to download the original model first. Inside the downloaded file, you will find a folder called "737's". Go into this folder and look for the folder "737800". Drag and drop this from the .rar onto your desktop.

Then open the folder and go into the dlc.rpf. Then you go in: x64/Levels/GTA5/Vehicles/eaglevehicles.rpf/, and replace the old .ytd with my new .ytd.

Then you follow the ReadMe from the vehicle, since you also (I think) have to make an entry in the "extratitleupdatedata.meta". Of course you have to Search the "737800" in the ReadMe. It's best to do this with "Ctrl + F" and enter the name of the 737-800.

Done!
