Delher Shoud Caps and Rigging Screws

[Scrimma]

Hi everyone. I have a 2000 Delher 39. My rigger is having trouble working out how to remove the round caps that cover the deck connection for the V1 and D1. The boat is being re-rigged in a marina berth, so removing mast is not an option. Anyone run into this design before and have images or an idea of how it all comes off and gets replaced?

The photos are not of my exact vessle as it's currently a monsoon here, but it's of the same make and model. I can get better close up photos in a couple of days, but the attached photos should explain it well enough..

(The uploader may be playing up, can anyone see the photos?)

Any thoughts/suggestions would be greatly appreciated.

Cheers

Hi, inside the boat there is a rod that holds this plate down. At the bottom of the rod is a turnbuckle, undo it, disconnect rod from boat and lift off the cap on deck. BEFORE you start all this, make sure the mast is held by lines.
