I had to take a quick look on this one.
The separate panel for the radio on the early cars is a separate piece. The later cars have a one piece dash.
I don't think that will make a difference. There is a partition by the speedometer that may be in the way of the steering lock mechanism. When I had the heater core repaired, I know we were not able to access the center of the dash from the speedo hole. So it may be in the way trying to access the lock mechanism, I just don't remember the exact placements.
Taking the tach etc. out, is as Chris describes it. I would add - be very careful with the temperature gauge connection. It is a sealed system. It can be repaired, but better to be careful upfront to not have to worry about. The oil gauge is also a direct connection, so if that is loose when you re-assemble, you will have a well lubricated leg!
