You should be able to use that 97 hard line, complete. You'll need to do some beating on the strut tower to get that booster in, and drill/enlarge a hole to allow it to pass through the firewall. On my 93, it just barely slid past the strut tower...you won't be so lucky. Also, keep in mind the 95+booster uses different nuts to secure it to the firewall, so keep them.
