Me too. Alldata discontinued everything before 1983. The only way now is to find a chiltons or haynes or a factory service manual.
If you're asking about eliminating the vacuum advance on the distributor assembly, I don't think you can eliminate that without a computer controlled ingnition system. The vacuum solenoid is used to advance the spark under higher load, and works together with a centrifugal weighting system that adavances the spark based on RPMs.
Linked is the diagram for a 1976 Cadillac DeVille, 1977 should be roughly the same...
NO vac pump in the '79 87&89 Brougham 85-87 deville 89-93 deville 86-86 eldorado 85-87 fleetwood 89-93 fleetwood 86-86 Seville
Depends on the year.
The crankcase ventilation tube is plugged, pinched or it has been eliminated.
