I am building a '50 two ton flat bed with a '33 Chevy cab. I will run an '86 292 with an '89 five speed and the two speed rear end. My question is about vacuum assisted brakes. We removed some sort of vacuum accumulator and brake lines from the chassis as it was all rotted out. Is new stuff available to replace it? Was it helpful? Is there a better way? I am using a combination clutch / brake master cylinder from a '60's era Chevy.
