I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.

The distributor in that engine can only be installed in one position. The hold down is built onto the distributor meaning when it is installed and the engine runs the computer is responsible for the timing. The distributor will move a little but won't correct major timing errors.
