Switching ground glass between Wista and Linhof

[bnasht]

My Master Technika Classic just arrived and i noticed the ground glass is very dark compared to my Wista 45D.

is it possible to switch between them?
is there something i need to know before i take both of the gg off?

thank you

I would not recommend this. Every single Technika or Master is fabricated and adjusted to the finest specific measurements..changing the groundglas could alter your focal plane.
one or 0,5 mm difference is enough.
When I want to brighten up old ground glas I sand it with silicium carbide 600.

Add the fresnel for the LInhof. Your Wista has one, the Linhof gg sets on very precise shims, lose one and you are in trouble
