brake MC interchange

["Marko Mataija" <marko.mataija@domain.elided>]

Brake MC on my Spider started to lose force, so I am planning to replace it
with a rebuilt one. I have a spare brake MC from another car (Giulia), which
I would like to rebuild. The problem is that they are of different types.
Both were manufactured by ATE, but the one in my Spider has a symbol "20"
stamped on the back, and the spare one is a "22" (I think these were also
used on Alfetta). They look the same from the outside. Should I expect any
problems with the change?
