For Winterized T-51b its in the Outcasts fort. You have to do a simulation like in vault 112, and the people in the fort will unlock the armory for you. Inside the armory will be all the best weapons and armor in the game. Including medical supplies, and a lot of ammo. Be prepared though, if you take everything the outcasts will attack you. For regular T-51b after the mission, "You Got To Shoot 'Em In The Head", kill Mister Crowley (I recommend doing it after he's left Underworld) and take the special keys. Then go to Fort Constantine and enter through the door in the basement of the CO quarters. Go through the under workings of the fort until you get to a room with 2 Very Hard locked doors. Find a raider named Tara and go through the door nearest to her. In that room in regular T-51b power armor with a matching helmet.

You can find the Fallout 3 Section 8 armor mod on platforms like Nexus Mods or Mod DB, which host a variety of user-created content for the game.

Always ensure to download from trusted sources to avoid malware.
the prototype T-51b power armor in Fallout 3 is designed just like normal T-45d power armor but it does not sacrifice agility for armor rating and rad resistance.
