Looking for American Road signs

I am trying to put some american road signs in the East Coast USA map but I cannot get any from other maps to work they have no texture

 

There are prop signs but there are only: Stop sign, Yield sign, 25, 35, 45, 55, and 65mph signs.
The signs you want are only found on WCUSA and there is 1 sign from Utah.

 

uh I don't know how to do that

 

not really anything yet

so I copied the folders to a new folder and it corrupted the map but the map was a copy so it would not mess up the main one so I need someone to do it for me and send me doownload
