need help with size of brake booster

[ec1981]

Hey guys, I can use some advice on which size brake booster to use.
I found out the hard way that a stock booster will not fit when I dropped in my 409.
What size booster or brake conversion do I use?
I would like to run the stock 14" hub caps.bang
Can you help?

I used an 8" dual booster with an offset bracket. The bracket that I used is offset about 2" to the left. I purchased the bracket from CPP. They have the bracket lised for use on '55 to '57 chevy's.
Another alternative, if you have power steering, would be to use a hydro boost system.
