I'm getting very close now to installing my Champion CC369 but can't seem to find the correct fittings for the tranny cooler built into it.

In the documentation for this, the fittings for the radiator lines are described as:
.....
.....1/2" 20 STRAIGHT THREAD G1/4
.....

I ordered what I though should work from summit but what I got looks more like the fittings that would screw into the 700r4 tranny, not the radiator. My old 4 core copper/brass radiator had the lines connected via two small brass fittings that made the connection from the line to the radiator. These fittings will screw into my new Champion radiator but they aren't going to make a seal as the threads do not really mesh very well and the fitting is loose once threaded in there ( like the threads are incompatible ).

What is the fitting I need for this radiator? In the pics below I'm showing the lines from the tranny and the brass fittings I have that will connect to the lines but don't really connect properly to my new radiator.

Appreciate any help you guys can offer here. Thanks,
