Switch over.

Yes, the switch over valve found on the rocker cover of 81/85 300Ds has 3 vacuum ports - inlet, outlet and bleed off. It's as small as a kickdown switch and could be fitted to most any cable or linkage. Plumb the wot bleed off back to the booster and you will have normal vacuum booster and modulator operation regardless of available vacuum.
