I'm putting in an Olds. 455 in my '86 Firebird and am running into some space problems. The brake booster is severely limiting the space I have on my drivers side. I don't think there's room to put in headers. So my question is, is there any smaller aftermarket brake booster I can use on my stock brakes to allow more space between the heads and the brake booster? Any other ideas on fixing this problem? Thanks for your time. (I have frong disc, rear drum in case that makes a difference in your answer.)

I don't know if they make sets for f-bodies, always forget to ask 'em However, this solution is quite expensiv, I think
