Brake Booster interferes with Inline 6 Air Cleaner

[Lugnutz65]

I was afraid of this.

So my brake booster interferes with my air cleaner. Options?
1. smaller air cleaner housing. Suggestions?
2. Fabricate a new air cleaner housing.
3. Swap to the weber 32/36 I have sitting in the box. (I hate this option at this point of my build because the Rochester B is rebuilt and runs perfect).

So, I'm installing a 1995 Blazer power brake booster and MC with a CatainFab firewall bracket (Nice product BTW!).
The air cleaner housing is not going to fit because the booster is in the way.
I bought (and returned) the really small Mr Gasket air cleaner part #4354 because it didn't fit properly on my Rochester B carb. It said it was for 1 barrel carbs but the base ID was too small (barely).
