Almost all of the original Direct Connection suspension parts were repurposed C body or Van parts. That is where the early NASCAR stuff came from. If you have access to the old Kit Car build materials you'll find a lot of C body, van and light truck stuff that was put on the ABE platform so what you're looking at is basically the same stuff. I'm pretty sure the "fast ratio" idler arm is just a C body idler but I don't recall exactly which make and model it comes from. Could be the same thing with the Pittman arm. It would have been easy for the Mopar engineers to grab a C body or van Pittman arm and stick it on the TA and call it a "fast ratio".
