It was suggested years ago to get parts from Cummins ,so I have.A fraction of what Dodge wanted. For instance the steel line running from heat exchanger behind block 138 at Dodge 42 bucks at Cummins . So I walk in and order the steel return line that has a brace and one bolt hole that runs fromheater core.......257 buks. Online they run 36 dollars. Because dummy me thought it some special one in a million made of stainless or whatever ,reluctanly I ordered it and got it the next morn. Shouod I take my chanses waiting by ordering online or take it back to Cummins unopened and have the regular parts guy reduce the price ? Because the regular guy was busy at the moment,I think the guy I dealt with doesnt normally sell parts because he was in an office in the back and seen me waiting and acted kind of annoyed that I was there. What I think is he sold me the part in their system as if they were installing it rather than wholsaling it like the regular parts guy does.
