Thanks everybody for your kind and encouraging comments, I'm more certain than ever now that changing my original dashboard has been the right thing to do. When you are the driver the thing you are looking at the most, other than the road, is the dash.
The ejector seat button is there for those passengers that like to ask those questions such as "how much did it cost ya?" or "what's the top speed mate?" or "is this imported?"
Here is my car from the side, it's in great condition for a 37 year old original 4/4.
