require the pave plugin which is incompatible with STARS 2.0 
(Note TOTNW 2.0 Isn't Properly Patched for STARS Yet)
but have open permissions as long as credit is given so i removed the pave master and rebalanced it for STARS (making it the best t-51 armor besides the juggernaut one 
it's balanced differently in relation to hellfire armor then in the original mod)
Description form the original mod:
"Requires TTW

So in TTW it's insanely easy to get powerful Power Armor, between the Hellfire Armor and the t-51b in the Mojave it's never been worth while to do the Fort Constantine Quest since it just rewards the player with another set of T-51b.

This mod makes it that the Fort Constantine armor is Unique, the T-51c Power Armor, a small upgraded version of the T-51b.

The armor is on par with HellFire armor with stats, but has more health than the Winterized T-51b Armors and gives the user a total of 20% Resistance to Poison, Fire, and Energy alongside the normal T-51b stats.

This makes the T-51c armor the best Power Armor in the game, which I think is fair for a wasteland-spanning fetch quest. 

Thanks to Fuse for finding the texture in New Vega's files. 

The textures are separate from the other armors and use a merged version of the default armor and the Winterized armor. This allows anyone to simply replace the texture with another T-51b armor retexture."
