I have seen your thread.
I have been revamping my interior and thought about buying a new one like yourself.
I have removed the original a couple of years ago like so
and replaced it with this
which I made for the Coupe long before I owned one.
I put the original knob back on the other day for a try out as I had gone from the sprayed matching central console and ash tray etc back to a by the use of plasticote black satin look.
Back to the knob. I went to pull it off and the outer came off. Hence the pics. It was easy to put back after I gave it a going over. Just thought that it might be of interest to see the makeup/internals.
The ashtray I replicated and have a lighter socket/micro usb and widget. It is (the fascia) attached by rare earth magnets to a strip of steel to make it easy to detach when needed.
