header-transmission line clearance issue.

I do this on my cars, and suppose you could do the same just as easy on a truck. I go to the parts house and buy some 5/16 steel gas line in 5' lengths, and run it up the drivers side frame rail. In my cars, I use a bulkhead fitting to get it thru the radiator support, and then make shorter steel lines to get to the transmission cooler. I use a stack plate cooler that has threaded fittings instead of hose bibs. I get 2 steel braided flex lines made to go from the transmission fittings over to the lines on the frame rail. No flex lines there would = cracked lines. The fittings you will need and getting steel braided lines made will run the price up a little, but to me it's worth it to get the lines over there out of harms way. If you have a place near you that makes hydraulic hoses for backhoes and stuff, they can make the flex lines and hook you up with fittings. Just an idea, hope it helps. :glasses7:
