Oh for Pete's sake... what size wipers do I have?

This question should be simple but is driving me nuts.

What size wiper blade refills does my 2000 Odyssey LX take? I can't
find it in the manual. I've been to a couple auto parts and
retail-type stores and the reference book they have either doesn't
list the correct model, or gives a wrong size. So far, I've tried 20
and 22 inch blades. It looks like 24 inch is the right size, but I
don't want to buy another set until I have it confirmed.

Where, other than a dealer, is a good place to buy the blade refills?

Also, what size is the back wiper blade, and is there any place that
would sell just a single refill like I'd need for that?

 

Is it possible to remove & measure them?

 

Uhhh, yeah (sorry for the sheepishness here). But I'm so clumsy that
I don't want to break the wiper getting it taken off. My guess at 24"
is based on I held some 22" ones, still in the packaging, up against
the ones on the van, and the van ones looked about 2" longer.

I'm hoping that someone reading this either just knows the answer, or
better yet, can refer me to a page in my Honda manual with this
information, or a web page with it.
