hose just looks like that, you have to stretch the hose over the ic, the adapter is a perfect fit for the hose.
another idea i used an ac condensor for a bigger ic radiator 27"x12"x1" thick
was for an old toyota truck. (works great) has the inlet and outlet on the same side and a 5/8" hose fit right over the ac fittings
oh and where i was looking to fit the ic radiator on my 185 was between the ac condensor and the radiator,wanted to keep the ac.
the 165 the radiator fit nicely up front and was able to keep the ac and the fog lights. i was even able to install a pull fan behind the ic radiator to help with keeping the fluid cool
