Dynax 9 disassembly

Hello friends,
my Dynax 9 needs a little service at the viewfinder- I'm fairly experienced with a few Minoltas such as older MFs,9000, 9xi and Dynax 7D but I wonder whether anyone has some experience dismanteling a Dynax 9 up to the viewfinder area,like from where to start?
thanks much for any input,
Dan
PS: Sry, just noticed this is my first post even though I'm registered since 9 years, so a big hello to all :)

Are you trying to get to the eyepiece bit of the viewfinder or the focusing screen side?

Yes, I'm trying to open up the eyepiece part with the diopter adjuster and viewfinder lock. It has some fungus right behind the glass and as it seems a little on the prism of that same side, and I'd like to clean it up.
