Master Cylinder gasket?

[Ms.Sully]

Hello again... Been chasing my brake issue and found brake fluid at the firewall coming from the MC. Before I pull this thing off and try to replace it, is there a gasket at the firewall? The replacement didn't come with one and I don't want to start this if I can't just finish it.

71 RR, manual drum brakes

Thank you for your help!
