Brake booster removal question

It looks to be there to me.....

Hi Cudamark
I suppose that you speak about the flange between the MC and the booster. I don't know if it's a spacer or if it's part of the booster body.
Anyway, it's not a problem. If it's a spacer, I will leave it on the booster.
My main concern is about the rear bracket.
If this bracket isn't needed for the rebuild job, I think I'm going to leave it onto the firewall.
What do you think?
