How would you remove the date wheel on this movement?

[AP1875]

This is the first movement ive had where there are no drawings available and no tutorials on youtube. I want to switch the date wheel for a white one. Due to the fact the chance of spares for this are slim to non, i just want to check with you guys how you think i should remove it? The spring inside the red circle is under a lot of tension.

Two areas that slide in and out

The only thing securing the date ring there appears to be the two points arrowed which I assume are part of the date change mechanism.

Given that the spring mentioned is locked under a cover plate it shouldn't be at risk of coming out. I'd suggest relieving the tension on each peg in turn and lifting the date ring gently, the new one should locate back in the same way.

Thank you for your help. It gave me the confidence to try it. This was literally the easiest date wheel to remove, i just slide the notch by the number 4 as you suggested and it popped out, pulled it out again to drop it back in. I'm wondering when i'll have the confidence to just do this myself without asking....
