Where to find garages, pitstands and muppets on GP4 original tracks?

Hi guys! I can't find muppets, pitstands and garages textures on the original GP4 tracks. Does someone know where to find them?

Ciao!

If I´m not wrong (someone will correct me) muppets are in the anim.wad (look in "anim\animationdata\qualifying\skins\ and anim\animationdata\race\skins\" file. And for the pitstand and garage textures on the original tracks you´ll find them inside the wad of the track (example, Suzuka: suzuka2001\maps\suzuka2001).
