Clymer says to remove the brake hose from the anti-dive. I need advice on this since I think I can just split it in half without anything leaking out and without removing the brake hose, correct?

Yes, the two halves have no hydraulic connection. This also is how you can remove the AD without using block-off plates.
The glass is not half full, it was engineered with a 2X safety factor.

Thanks for confirmation. I seemed to remember that's the way you do it, but better to ask than to have brake fluid or something all over.

Was in the bike shop recently having a chat with the proprietor while he disassembled forks on a Gold Wing and discussing the ''special tools". Back in the day when these tools were very expensive and the dollar was worth a lot more he and I came up with tools for forks, He showed me a draw full of them. iI still have the long square section 3/8 rod with an appropriate size nut welded to the end for my old Can-Am (a good hardwood square stick filled in) with the White Bros forks and length of split ABS for driving seals. Cool made to order tools would be nice to have though.

Thanks out to those that shared here and in other threads.

I did what everyone suggested - I googled the M18 bolt and the local Tractor Supply showed them on hand.

Added bonus: Chick Days

Found the bolt pretty quick, I think it was $6.00 with tax.

Used it with Vice Grips to loosen the caps.

Pounded a 5/8" 12 point 1/2" drive socket onto the end and extensions to reach up into the forks.

All good.

It's a nightmare. I did my best. New seals new dust rubbers. Take all apart (left hand side only, RHS perfect, no leaks).
Finished. LHS immediately leaks again.
Oh my goodness what do I do?.
Oil pools under wheel.

Did you replace the bushes as well, or only the seals and dust rubbers?

Sounds like either you haven't got the deal in squarely, or......... if it's just oil pooling on the floor and not oil coming past the seal and running down the fork leg, are you sure you haven't just got a leak from the bottom bolt or the drain bolt at the bottom of the fork leg ?

I feel your pain.

Inspect your upper legs. I found a tiny little sharp spot/scratch that I carefully removed with some 1000 wet/dry sandpaper.

So far, so good.
