In 1968, you only got a small portion, but it was still spaghetti

If you've never spent a Saturday afternoon trying to figure out which vacuum line goes where on that '68 Cougar you bought from the guy who thought his vacuum system modifications would improve things, you're very lucky.

The fact is, even Lincoln/Mercury's technicians needed occasional help when it came to untangling the spaghetti-like mass of vacuum lines under the hood of the '68 model line. In that battle, they had a special weapon at their disposal that you can now add to your personal Cougar arsenal: the 1968 Lincoln/Mercury Vacuum System Diagnostic Guide. And to make things easy, we've also made a handy PDF version that you can download and save to print out as needed.

Hopefully, they'll make the spaghetti a little less frustrating.
