Top fitting toilet seat fixing removal

[cluelessX2]

Need some help please. I have removed a top fitting toilet seat to replace it. The old fixings appear to have a silver cap covering them, at least I assume its a cap, I cannot separate it if it is a cap. I've tried leaving it with WD40 and I've poured warm water on it to expand the cap. The fittings themselves sit on a rubber enclosing washer and oneside spins around the other doesn't move. Would it be possible that the spindles that held the seat are fixed to the silver cap plate and be screwed down from the top ? Any suggestions on how to remove them greatly received

Have you tried to unscrew the silver cover ,or are you trying to prise it upwards ?

Hi, I've tried to prise it up and unscrew but the fitting under is just spinning too

The silver "disc" appears to have a split line near the top, then another silver part below ,and a rubber seal below that ? If that is so ,prise at the split line.
A close up ,in focus , would be useful.

There looks like a small section on the chrome ring that you can push in?

I can't see any split line on the disc, it's solid . I think maybe it looks like it due to the rubber washer that goes half way up the disc.
With regards the chrome half ring, that comes out but doesn't seem to make anything loose and I'm a little lost on the purpose of it.
I think the only solution maybe to cut through the disc and prise apart

Does the upright part unscrew?

The lower piece is clear plastic just looks like metal in photo .

I wonder if the OP is trying to lift both? as only the metal cap will lift, flat screwdriver between the two.

Is it a trick of the light ,or is the vertical post made in two parts ? The top half looks like chrome and the lower half a darker colour ?
I wonder if the little clip thing has to be removed in order to separate the 2 sections. When fitting the toilet seat ,what does the little clip do ??

Thanks to everyone. Hacksaw was the way to go in the end.
