Just wanted to give an update. I ordered these lines from Inline Tube. They are part number DTT8731. I used their online order form and said I had a 85 W250. And just to be clear I typed it out in the comment section... "1985 Dodge truck 3/4 ton 4x4 trans cooler lines". What I received was completely identical to what I removed from my W350, so very happy with them. ITs funny that the tech line told me the 1 ton 4x4 was a "completely different animal" and they didnt have a pattern to produce them.
