Tatra 603 dff only mod. Original author is Huckleberry Pie. Ported to Android by Los Santos guy.

The Tatra 603 is a large rear-engined luxury car which was produced by the Czechoslovak company Tatra from 1956 to 1975

I've included two methods for installing this mod:

The simple method. (dff only) The only thing you have to do is replace glendale.dff with Img Tool Android
and move the file called 'txd' to Android/data/com.rockstargames.gtasa/files/texdb. This is a primitive
method. Because it's possible that you already have a file called 'txd' installed for another mod.

The Txd Tool (Android) method. (This method is the best) You have to import 'glendale.txd' to 'txd.txt' with Txd Tool.
(And of course replace glendale.dff with Img Tool Android)
I've made a tutorial on how to use Txd Tool: https://youtu.be/JNneVjkbxJM
Good luck and enjoy!
