If I'm following correctly, yours has the factory cooler in the radiator and you added the Trucool inline with it?
The way I'd like to do mine is to get OEM hard lines for a model with the factory separate cooler. This cooler mounts in the same location where everyone puts the Trucool and the connectors are on the bottom just like the factory cooler. The Trucool is wider, so you cut one of the factory lines under a bend, rotate it 180° and reconnect it with a compression union. It'll be just like the factory design, just with that union in place, but that's still better than rubber hose and worm gear clamps.
