I believe I got mine from The Right Stuff (getdiscbrakes.com/transmission-vacuum/transmission-cooler-lines). I talked to Curtis. There's also inline tube. I'd heard that the right stuff lines fit better.
Now the oil pan for the transmission has dried. I got some areas with more and some areas with less. Just as the factory did it! This Cosmoline thing smeels old right from start! I'm really satisfied!
