Cannot Find Texas Half-Pants or Razorback

I’m having trouble trying to find the Razorback for the Sniper and the Texas Half-Pants for the Engineer in Garry’s Mod. Are they hidden somewhere in the files or are they part of the bodygroup for the Sniper and Engineer? I need to know this because I’m planning on doing a Garry’s Mod short that introduces a character of mine that’s based on the loadout I use for the Engineer. Any help would be appreciated.

The Half-Pants are in player/engineer.
The Razorback is in player/sniper.
