Transmission lines - HELP!

[dmw319]

I was replacing the two lines from the transmission (th350) to the radiator and I bought these:

It says that they come with 2x 5/16" inverted flare to -6AN male fittings and 2x 90 degree 1/4" male NPT to -6AN male fittings. The problem is that two of the fittings do not fit (the NPT ones). I should have bought the 23-1501 that comes with 4x of the 5/16" inverted flare adapters...

So without returning the hoses and getting the right set, does anyone know where I can get any adapters that are inverted flare to -6AN male? I looked online and didn't come up with much so didn't know if a different type/style would fit? Without these I am dead in the water without a vehicle and I couldnt find anything at my local part store.

Also, I'm assuming the 5/16" is referring to the hose size and not fitting size, correct? If so, are these the right ones?
