Where to get trans cooler line fittings?

Being on a rock in the middle of the pacific limits my pars resources and hoping someone can help me with the following...

Reinstalling the factory style transmission cooler lines with auxiliary Hemi trans cooler.
I purchased the repro trans cooler lines however they did not come with the brass block that connects the two cooler lines just below the aux trans cooler.
I also need the two fittings that go into the radiator trans cooler which the lines connect to. They do not appear to be the same NPT type fittings like the trans fittings.

Any help would be greatly appreciated.

Thanks!

Oh yes, this is for my 1966 426 Hemi Coronet

A had the same problem as you a number of years ago and ended up sourcing out the small brass fittings for my cooler lines through Diotte Hydraulics. Is there a place local to you where they can make up hydraulic hoses and service hydraulic parts? I would start there. I wouldn't be able to help you with your brass block if you're going for the OE look but if not, your hydraulic hose retailer could help you out with that as well.

Got you covered. Doorman female inverted flare Union #070660BP SKU 019495371342

Bought from local O'Reillys auto parts.

The fittings in the radiator should be the same as the trans. Do you have an aftermarket radiator?

Aloha! If the Doorman union doesn't work out for you, how about Hydra-Air Pacific over by the airport? They made a couple lines for me and might have a good selection of fittings.

Thanks everyone for the input!
I have the factory original Hemi radiator in the car.
Randy, thanks for bringing up Hydra Air, forgot about them. Also have D&M.
