Tremol-no for majesty 7 String

I’ve been looking to install a Tremol-no in my 7 String Majesty. Do any of you guys have experience with that? I’d love to hear what you have to say about it.
I think it needs the Pin-Type tremol-no, but will it also work for the 7 string bridge?

Sorry if this question has already been asked, and thanks in advance for your responses
