How to remove 7 speed DA cassette
I have a wheel with a 7 speed dura ace cassette/freewheel. Where you would normally enter a cassette tool is a plastic cap with 2 holes for turning with a spanner wrench. It has an arrow pointing counterclockwise to open. This cap spins and spins forever with no effect.
How would this be removed? Is it possibly a uniglide (?) that you unscrew the small cog with 2 chain whips?
Thanks in advance

I should of clarified, the holes arent all the way through they are just indents. I'll try to find a second chain whip and give that a try.

pop it in a frame, use the crank as the 2nd chain whip.

Yes, the small cog unscrews.
When you remove the cogs, you will find that each cog is separate. This was good because you could buy separate cogs and build it with the gears you wanted.
You can likely find the separate cogs on EBay.

No, you can use standard cassettes. You just need to keep that 1st top cog that spins on to lock the rest of the cassette in place. You can fit modern Hyperglide cogs by grinding down and widening one of the grooves on the cassette body:

However, you'll only be able to use 7-spd clusters. Replacing the freehub-body with an 8-spd DuraAce one is possible, but that's it for upgrades. The 9-spd & later DuraAce hubs use a different attachment method and you can't fit those freehub-bodies onto the older h ubs.
