Yesterday I mounted mine vertically (only space I have with the oil cooler there) using the existing center brace in front of the condenser, there's even a free threaded nut to use. I disconnected the OE top cooler hose and used a brass 3/8" mender to connect it to the new line and ran hose to barb on the Hayden. For the bottom hose I ran from the Hayden toward the drivers side, cut a piece of the radiator core support out to ease the bend (2" sq. max), cut the lower hose where it affixes to the radiator fan shroud and used a 3/8" mender to connect the new hose to existing.

Do yourself a favor and use Awab hose clamps size 17.
