The holes in the firewall need to be slotted to get a sn95 booster in, or you can get a 1993 cobra booster which is the same but with a fox stud pattern. You still might need to slot as it's a physically larger booster,
As for the mc, you need a 3-2 conversion to run a two port mc. There are a few different ways to do this.
But it can be done. I have them in my car with cobra disk brakes
