Working on a 1978 Buick Regal Turbo 3.8L 4bbl. Looking for a vacuum diagram. Checked beforeblack.net but links are no longer in service. Any help appreciated.
Thank you! I did some further snooping on beforeblack.net and found if you goto http://www.beforeblack.net/images/ you can find all the vac diagrams listed. I guess the links were never updated when the site was moved? Does anyone know who runs beforeblack.net? perhaps we could suggest updating the links...
