Vaccum lines for 4x4

Does any know where I can get the hard lines that control the vaccum for the activation of the 4x on a 97 Dodge ram 1500? The CAT overheated and destroyed them. I called a few auto yards and was informed that lines are not priortiy to them in teardown. They have no parts listing for them. I know I could probably use brake line but I prefer not to. I currently live in Germany and as some know they don't have many AMERICAN made trucks here. Any help would be great.

you could use any type of rubber vaccum hose and secure with tie wraps but not too tight
