If you are OK with it being a three piece assembly, go to a hardware store and buy two barbs and a 90 and screw them together.
I know my local Ace Hardware sells the parts.
I went this route and I had to solder them or they leaked. Just an idea but you can solder them.
They have preformed lines for the 6.0 trucks. Some guys have used the OEM 6.0 cooler lines. Most just use cooler hose. When I installed mine, there was no need for elbows there, but I understand why people put them in. If you take your time, you can get it installed with no elbows.
Hey ken , I am the process of doing the 6.0 cooler and see that you have heard of guys using the 6.0 lines. I have the 6.0 lines do you have any tips on adapting them to the 3/8" lines? I would like to use somekind of bushing on the line that screws into the radiator.

I would use 3/8"-1/2" flareless adapter. You should be able to get them from any hydraulic or industrial supply. Swagelok is a manufacture that builds them. You can get them in stainless steel or brass. You may find brass ones at the hardware store too. They are usually built lighter duty, but will probably work fine.
The flareless fittings are easy to install and provide a leak free connection that can be used as a disconnect point in the future.
