I've seen a drawing of the separate bits in some sales list somewhere ... sorry, can't remember ....its actualy the speedo/rev etc...walnut srround i need
So can you buy these or is it built in as part of the clocks ?Keep looking
Like Teapot says, the surround around the clocks is a seperate piece and is held in place by three small brackets on the reverse. The clocks are not part of the surround, they are simply screwed to it , again, from the back.
Just done something similar in my Cooper Sport. Previous owner had enlarged the dash vent holes and fitted speakers in place of the vents >

I was looking for months for a dash but, eventually one turned up. Keep trawling through ebay, you'll get one sometime.
