The bottom radiator hose took the longest to get right, but I ended up using 2 stock 6 cylinder hoses on the water pump and radiator and then cutting the hose I had grabbed with the junkyard radiator and using it to connect the two.
We made it to the Downtown Tulsa Cruise with the 1971 Mercury Monterey and the 1975 Ford E-150 Econoline, finally got 2 out of my 4 Fords in the same car show for the first time!
