There are 2 style headers:
1. GTA V
2. GTA SA

You can see some differences between two styles in pictures. For more information you may look at images in menu folders.
For example, in gta v style Los Santos Customs header has been used for all modification garages.
Special headers have been used for every mod garages in gta sa style.

I have mixed different images from different authors to make great experience. I have made menus.dat and some images. Thanks to other authors:
