Agree with 3B. However, hydro boost systems are very simple, pump off GM and others, brake master assembly same place, need deep 15mm socket to get master off firewall. Several factory lines available or make up new lines. Need to get master input shaft properly adjusted. No need to fool with lines or slaves.
