My tool of choice for this procedure is a piece of full round dowel from a
lumber supply house that doesn't need to be any longer than about 6"  You
might find a scap piece on the floor for free.  Diameter needs to be at
least 3/4" and can be bigger.  I create a dimple in one end of the rod to
rest on the ball socket(empty on most vanagons of that vintage and even if
there is cruise control linkage on it, a slightly deeper dimple will do the
trick).  The other end of the dowel is cut at a slight angle after
measuring the distance between the ball socket and the front lip of the the
engine lid cover.  You'll have to play with this a little. I then cut some
shallow slits up the angled face of the cut end with a hack saw to give the
throttle prop a little room for adjustment.  Has worked well and only a
couple times has it vibrated out.

My two cents worth
