Transmission cooler lines

Howdy gents,

I have an issue that I am not sure what to do for.
I had to replace the transmission cooler lines, I bought the replacements from Classic Industries and now that I have them mostly installed it does not line up. I have attached pictures to help me explain.

I do not know if the radiator is stock I am leaning towards no, but the model number that is on the radiator is 33497

My vehicle is a
1974 duster with the 225 slant 6.
The first picture is from the rear it is the return line. It does line up with some help.
The second picture is how the lines route from above.
the third picture is how the lines line up to the radiator
The fourth picture is from underneath. With the lighting you can kind of see the where the return line is supposed to go. I have only had my duster since October and I would like to get it on the road by the 21st. but we will see.

So I guess my questions are

1. did i line things up wrong?
2. is my radiator not the right one?
3. should I just go out and buy a flexible line?

Thanks in advance for all of the help.
