Question: I have a bathroom faucet with wide set taps made by ‍ who knows?

They are all messed up and I need to swap them out. But I simply have not been able to figure out how to remove the taps. The taps are metal with side levers like so:

They have a vertical set screw and with some WD40 and a lot of swearing, I managed to get the set screw out and pull the main tap handle off. But now I have a wide piece that I don't know how to remove to pull through from the bottom:

Conversely, on the bottom, there was a plastic nut, which I loosened as far as it would go, but that didn't free it, because it's screwed onto a t-shaped piece (you'll see that the plastic nut has been loosened as far as it will go, but cannot be removed). So I can't pull the copper T up to remove the tap either:

I'm at my wits end. Can anyone tell me how to get this thing off?

Answer: 
Next step,

Fist look it there is a pin here to pull out.

Then use correct size toll and unscrew the nut (marked with yellow lines) that is holding the ring down.

Remove the hoses from the "T-shaped piece" and unscrew it.

Then smack the exposed end with a mallet, upwards, if it hasn't come loose by itself at that point.
