How are RC-10 Shocks Sized, Now?

[HS-YZ250]

Dumb Question:

I have a long term build project I started back around '07/'08-ish, when RC10 shocks were pretty common. Then,Associated sized their shocks by their stroke (.71 in, .89 in, 1.32 in, etc).

How are the new metric shocks sized? Still by stroke, and I match a shaft to a body?

I got the idea that they may be sized by overall length. I'm looking to replace a set of shocks with about a 0.71in stroke

Thanks!
