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.
 
This is what I have for an 83, might help, might not. I"m sure it came off of the B4black site a while back.

The 1979 or 1980 diagrams should be very similar if either of those links works.

They come from the factory shop manuals, which sell on ebay for dirt cheap.
 
Unfortunately the 83 won't work, it had an ECM where as mine does not. Anyone else have anything from 78 to 80?
 
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...

I put the site together, and it was moved by someone else.

I need to move it again, but don't have the tech savy (or time) to do it. I need the help of a twelve year old. ;)
