I have a 1990 VNT Shelby Daytona and the vac lines are beyond repair. I have started the process of doing a vac block set up and am going to use nickel/copper brake lines as vac lines instead of hose or plastic (hopefully it will look a little cleaner that way). Just looking for any advice or things to look out for from anyone that has done one themselves. I have the FSM and have found a few diagrams and threads on here but any additional resources/pictures would be great. Will post pics when finished. Wish me luck!
