HD Texture Pack Question

[Genkster]

I want to replace the textures for Gran Turismo 3 - A Spec and have the texture pack for the game (SCUS-97102). The ISO I have for the game has the serial number of (PBPX-95503). My understanding from replacing previous textures is to rename the folder of the texture pack to match the serial number of the ISO...being that my ISO serial number is different than (SCUS-97102) how do I name the texture pack folder? Do I just name it (PBPX-95503) and it will work as it should?
