Direct Connection K Frame I.D.

I have what I believe is a direct connection k frame for a big block dart. It’s set up with spool mounts and was installed on my 73 Dart big Block. I am going to be selling it as I am going to a tubular front suspension. I will have upper and lower control arms, the k frame, and the strut rods. What I would like to know is how to identify it. Thanks.
