My 79 distributor has the vacuum retard side disconnected only, but the static intial timing at idle needs to be set at 10 degrees AFTC in order to prevent pinging. I think the original owner did this when all the emissions stuff "fell off"....how convenient.
Vacuum advance still functions.
Careful when messing around with this stuff as the turbo is extremely sensitive to detonation under boost, and total advance is a critical value.
