Unfortunately I cannot help on that issue. I haven't had the need to tear down the forks on my AK.
On my last 3 bikes I solved the leaky fork seal issue by using a Seal Mate tool. It's a very thin shaped plastic tool that you hold around the fork tube and slip up past the oil seal. Most leaky seals are due to grit that gets between the seal and the fork tube. Of course you slide out the dust seal first to be able to get to the oil seal. Slip the Seal Mate tool up between the oil seal and the fork tube and slid it all the way around the fork tube.

I have not done this.  My usual deal with forks is just doing the oil, not pulling 'em apart.  I think that rjs's idea might well be worth a shot.
That noted:
Looking at the assembly I see the top cap (94605) and the bolt on the bottom 9660.
The top one I usually leave in the triple tee clamp to loosen initially and finish loosening in my clamp table.
The bottom one I'd have to get an eyeball on. I know those can be tricky since they like to spin.

This upside down forks are a little bit trickier than the old ones, but...
