Good Evening Rocket,
I replied to your post this morning and later went back to look at it but I could not find my post. I thought that maybe cause I am a newbie it may get filtered but maybe I just never hit the submit button. ( not the most computer literate) Anyway, I believe that you have a anti-theft device. As you know, 70 was the first year of the lockable steering column. It appears that the Federal Gov. were implementing some anti-theft tactics and I think that is what you have. The picture of the bell housing looks kind of like a automatic kick down linkage. There is also a lever coming out of the steering coulmn that hooks to it. Above the keyswitch there should(may) be a little lever that says something like "turn to release key" The shifter was supposed to be in reverse before you could get the key out. Also, one had to put the key in before you could get it out of reverse. Most of these were scrapped for more header clearance. (What a surprise, huh?) Was your car originally an automatic and someone switched the stuff out of a 70, maybe? Not sure why it would be in a 69... Ironically, pick up the August '13 edition of Mopar Action. There is a great article labelled "Chain Linked" that appears to be exactly what you have. Let us know if this is the case! If you can't find the mag, let me know and I will try and send you the article. I may have better luck rebuilding a 727, though! As mentioned, not a computer wizz! Good Luck!
