[urgent] quick diff question [open / lsd]

[GeenIdee]

Hey guys,
 
Ordered a KAAZ 1.5way lsd for my turbo II, but got the question if it was an open or viscous diff.
 
I assume, that KAAZ needs to know if you have an OEM open or vicous diff.
 
So i am a bit suprised about this, because what i read here, is that you cannot put a viscous diff in the housing of an open diff. Is this true?
 
 
In that case the next thing would be to figure out what i got, and obviously, i am not ready yet to open the diff housing. So i got some information a 1 or 2 years back about how to see what it is from the outside. But because different people say different things again, i would also like to aks you guys if you can confirm this next thing for me:
 
Is it possible to see if it is an open diff or an oem viscouse diff when you pull out the diff output shafts and you look tinside the diff it self. And is it true that in case of an open diff you should see a shaft, and in case of an lsd you could look through the diff?
 
Thank you

Edit,
 
pic shot 1 or 2 years ago while replacing the seals. I thought this would mean its an open diff

Jack the car up and turn a rear wheel
If te opposite wheel
Turns in the same direction you will have a vlsd

If it turns the opposite direction you have an open diff
