rusted power steering lines at rack..
 

I`m new and need help. My power steering line is leaking cause of rust at the connection at the rack. So difficult to get at the connectors because of the front diff...this is an 03 Dakota SLT. Does anyone know the size of the fittings...use a flair wrench? metric or regular? I`m afraid to break off the rusted fitting in the rack, that would`t be good! Thanks Pete
