Naa, just a little late on the gun on that one as someone posted the full FakeBook AD up in the 'Not Mine' section.
But a pretty nice 'White' steering wheel example is good for archiving here ya'think? (full unbroken horn ring too)
1977 Chrysler Plymouth Dodge Electrical Service Manual - $30 (nanoose bay)
I've seen many CL AD's from this seller way out in the west coast that has many factory service manuals (FSM) for sale at very reasonable prices. I think I paid about this price each for my FSM's in the 70's & 80's right from Chrysler.
There were a lot of people including the Federal Government that couldn't figure it out. They pretty much outlawed the push button feature when they came out with a law standardizing shift mechanisms in the mid 60's.
