Need some help...booster,MC, brackets, gaskget question please

[ChevyDude]

I am upgrading to PB and am wondering if a gaskget goes between the MC and the booster (I have a double bail MC) and a Delco/Morraine booster. Second, if the vacuum hose deal valve goes on the left towards the motor the Delco Morraine reads upside down..is that right? And can someone provide a picture of exactly how the proportion valve and it's brakets and supply lines from the MC bolt up that would be great. I have sprouted a few gray hairs on this one and only wish I would have taken detailed pics prior to disassambly. Live and learn. Thanks guys.
