A/C accumulator check valve

While replacing my 1990 4.0 Cherokee accumulator I found a check valve assembly threaded onto in the out port of the accumulator. It goes to the small diameter line to that attaches to the expansion valve.
Does anyone have an exploded view of this check valve? I want to make sure it is assembled correctly. It is a two piece brass fitting with two spring loaded check valves.
I have a picture and will post it as soon as I learn how.

I would like to replace this part as I am replacing the entire system. Can't seem to find a part store that sells it. Any ideas?

I tried rockauto & jeepair...

It's not a check valve. You don't need it.
