I too found this out on my 89 wolfy, much quieter than my 85 or 87 syncro.
That rubber strip is a hefty piece of rubber too.
While recently at a junkyard I pulled one out of a 90 for my 87 syncro but
you CANT put them in.
VW welded a channel the full length of the door jamb to insert the rubber
into.
I suppose you could fab up a channel and pop rivet it in

Somebody should market an aluminum channel that fits and offer a retro kit.

I know my vans got louder when I ripped out the front carpet and the floor
insulation to put in the factory full rubber mat.
Perhaps doing a heavy duty under coat under the front of the van would help
.

What about those plastic rain gutter strips, they help?
