Thanks for the non answer.
I found the real answer in the service manual, which I own, but there's no good search function.
Anyway, there is a little plastic cap near the shifter, remove it and push the release inside. Obvious once you know it's there.
(I'd answer the original question, but the system won't let a person answer his own question.) - jim3not
One of the all too common problems with Chryslers of this vintage is that the so called key, won't turn. Thus no ignition on, no start, no drive. With the front wheels locked in park and the front end inaccessible, you can't even tow it. Un-locking the wheels, allows it to be pushed or towed clear, and then towed in the best way, with front end lifted, - jim3not
