[1000mp] key click Field

[VE2RYY]

Hello 
Is there anybody in this group who made the keyclick mods for the Mark V field?
If so I would like to know what MOD...INRAD or W8JI? Or another one??
I am a  little bit confused about the mods..  I was told that the MP mod was not the same for the FIELD..etc etc ...this is not clear in my mind...
I would be interested to talk to a guy who made the mod in his FIELD for the keyclick.....
Thanks a million
