Use the correct end on the tube, or find an adapter fitting. (I have NO idea who would make an adapter fitting.)

How would i be able to put the right fitting on the end?

An do you know what size the fitting is for the oem radiator?

It appears to be a Saginaw fitting. likely 16mmx1.5 thread aka 5/8x18. The threads are so close they can be interchanged.

It would work but it's clunky and expensive. See if the local auto parts store has a Saginaw to hose barb adapter and use a short piece of hose to connect them.

In the long run simply using an external cooler may be your best bet.

I would only need the reducers correct?

No. You would need both. the Borgeson ones are to convert it from Saginaw that seals with an o-ring to an inverted flare cone seal.
For those to work the radiator must have 16mmx1.5 thread and the hard line is 1/2" x 20 thread.

Those adapters are used for power steering pressure lines so they will certainly handle the pressure.

When you tighten a flare fitting of any type there are a couple of tricks for a leak free connection.

1) Use a drop of whatever fluid is going to run through the hose the lube the threads and on the tube under the nut. This makes it much easier to assemble. Except for fuel lines. Use a drop of oil for those. Preferably 2 stroke oil because it dissolves in fuel and burns clean. NO SEALERS OF ANY KIND EVER! Sealers are for tapered threads. That type of fitting seals in the threads.

2) Tighten the fitting 4 times. Notice I didn't say use a 4 foot breaker bar and break the fitting off!

The idea of this is if you snug it up and then loosen the connection3 times you will burnish (polish) the sealing cone and when it's tightened the last time it will seal. You don't need to make them excessively tight. And if you do use the adapters put the fitting into the radiator and tighten it properly as outlined earlier and hold that fitting with the wrench while you are tightening the line into it for a leak free seal.

One last tip, make sure you can thread the fitting into the other half at least 2 preferably 4 turns without a wrench. If you can't it's either cross threaded or it's not lubed.

Going to bed now. Back in 11 hours.
