School me on Pittman arms

[BriceRoad]

About 20 years ago I bought a Pittman Arm for my car from eBay. I think the seller was called "Rare Parts". I have always wondered if it was the correct part. Recently a different seller on eBay was selling Moog Pittman Arms. I bought another one.
The two Pittman Arms do not look alike but might do the same thing. The one to the right is the older one from the 2000s. I don't think either of these arms is the "fast ratio" Pittman arm. Which one do you guys think is the correct one? Or are both correct?

I don't know why the pictures got twisted 90 degrees or why I can't seem to put them into the thread.

Both look correct in the areas that matter enough they don't look the same. The older one looks like it was installed at one time. The newer Moog arm might be a Chinese copy. Sigh!

The older Pitman arm with the forging number 2835378 is an original Chrysler part, number 2835880. It is also possible it is an old TRW replacement part with the same forging number. The part has been installed and used. It is the correct arm for a 1970 - 1972 E-body without fast ratio steering.

The Moog Pitman arm looks like a replacement for the same application. The original Moog number K-780 was discontinued years ago. This might be a re-issue or reproduction, and as noted could be made in China, but I see current listings for one in a newer style box shown as made in the USA.

The pictured Pitman arms are not the longer fast ratio arm. An original fast ratio arm has the markings shown in the following image of one from my T/A Challenger:


It appears that your pictures would not post in the thread as images, but only as attachments due to the pixel size being too large for the FEBO server settings. I resized them and re-posted here in my posting.

Thank you both for the responses and thank you Gary for the in depth response. Yes, the part was used by me. I installed it around 20-23 years ago and I have put about 15-20K miles on it.
I decided to re-install it. I plan to drive the car 3 hours to Carlisle on Thursday and I don't want to take any chances. I think the old arm is still good. I just wanted to be sure it was the correct part. I remember it coming in a plain plastic bag with no writing on it so you may be right that it was a TRW part. Hopefully, it was a new old (TRW) stock part that just didn't have a box that someone got a hold of back then.

I looked carefully at the box the new Moog part came in and it doesn't say "Made in the USA" nor does it say "Made in China". The strange thing is there is no part number on the box and inside the box the actual arm was in a clear plastic bag that says "Mopar Genuine Parts" in about a dozen languages. I hope it isn't a Chinese knock off but I really don't know.

Thanks again guys.
