Yes, the 91 heater box will fit in an 86 van but you need to know that
the side hose connection points on the plastic heater box are different
starting during the 87 model year. Those 2 hoses are for the vents at
each of the dash, the ones that have adjustable grills on them.

Many later boxes have both side hose connection locations molded into
the box and if so you can choose to use the location that matches the
hoses you have in the van. That means you may need to cut the plug out
of the ones you want to use and plug the holes you don't want to use. An
important issue is that the side hoses are sized and shaped differently
depending on which side location they are meant for so you have to use
the box hose location that matches your vent hoses.

The difference of the side hose locations is this:
Originally the dash side vents carried only fresh air that was never
heated. During the 87 model year that was changed so the side vents only
carried air that had passed through the heater core and thus if the
heater core is hot that side vent air will be hot as well.
