Fork Size For Kona Stinky

I've got a friend who wants to replace the forks on his 2004 Stinky as they are totally broken. I can't work out what size forks he should be getting though. I think the originals were 150mm dual crown horrible Marzocchi things but I honestly have no clue.
Would some Revelations be the right fork to get or maybe some Lyrik's?

Uses it for recreational DH seems to work quite well
Revs will fold in half on the first jump
Lyriks nice but ££££££££££££££££££££££££££££££££
I know Rev's wouldn't break because the biggest jumps he would even look at doing I do on my Marin with 32's with no problems.
It's going to be difficult to measure the forks as he is moving house at the moment and it's all packed away hence why I asked here. He ideally wants all the parts ready so he can just give me the bike, fit them and then he can have it back within a few days instead of having to wait for stuff to arrive.
