So, I used the "4ft" and "5ft" 51" and 58" pre-made steel line w/ fittings from o'rielly's, did as few bends as possible, easy to bend by hand, the ones I did do were as lazy as could be, mock it up with wire to get length at the bends. Ran straight down the frame rail, rubber hose to cooler out front. Worked out great in car. The lines came 2" short of the core support, right beside my 26" radiator and still have access if you adjust the hose clamps in a creative direction. It's stupid simple that way.
They are secured by the k-member and prop valve. Good enough. Job took me an hour.
