They'll be 395mm I should imagine.
Go with the shortest shockers you can find, knock twenty mil at least off the stem (which is probably a tiller anyway) and bring the saddle slightly forwards to compensate for the relaxed seat angle (might need an inline but I doubt it) and it should handle okay. Depends whether you're happy to lose an inch or more of stretch though.
Trying it with a DynaTech and Amp F3 at the moment, will be a few days before it's rolling though..
