A904 Cooler lines with 5.9 Magnum- like a demented puzzle?
I did my 73 Satellite last year.
I used "fine lines" brand IIRC, and there was a difference in the bends that made the one that was tight to the trans, now go under the linkage, and the right/left connections on the rad were swapped.
I can only guess they made those changes make installation easier, and even then it was kinda challenging.
I had to fish one back out and go from the other direction.
Didn't have to remove anything though.
