I've got a PS box off a 69 Dart...... but I have never seen a PS
box with a keyway. They are all splined on the column side and the
Pitman arm side, as far as I know. PM if interested.
I've never seen one with a key either. Always splined
looking for a "threaded" power steering box for a 71 Duster. Most PS box use a key way.
Please let me know if you can help. FYI- I'll be going to Carlisle.
Thanks,
Todd
