The gaitor I have fitted has the clip in base, it looks like the type I need is the stretch to fit type.
TBH I was surprised I was given a rubber coated ashtray as the finish doesn't match the rest of the console plastic. I'll buy another lid for it, it's no biggie and easily changed.
You say the cage isn't needed but looking back in this thread at the pictures of one with the cage then surely it is needed as what's going to support the headunit from moving / tilting downwards?
