Please see the picture below. I pulled off the column drop (this is the only part I have) and looked at the back and there is the DPCD cross on the back. Since the motor was sourced from a 57 Imperial, back in the day, I am wondering if the steering was also? Does anyone have a picture of one or know what year? There is a number on the back also but I left it in the shop.
The number will tell it, though a better photo would also help. Mopar used that general look for a lot of years.
