Master cylinder to firewall gasket?

[68converted]

Is there a gasket between the firewall and the MC? If not what type of gasket maker can I use? Is RTV Black resistant to Brake fluid?

No gasket is needed. MC simply bolts to the firewall. No brake fluid is involved here.

I went back to the big green book and answered my question. I decided to use gasket maker anyway though. I would hate to have water seep from the hole. I would hate to even mess with the new floor pans; a little precaution. Thanks for the reply though!!
