I called Inline Tube to confirm the CTB4801 1948 Manual Brake Line Set 137" WB 2wd Long bed 1 ton 7pc Stainless at $180.00 and they told me that it will NOT work with a dually (that's what the 2wd means). So... I am going to pull all the lines and t-connectors and send them up there for them to reproduce. The guy said it would be about 20% more on top of the $180 to have them custom build the lines for me. So far so good? lol
