Spoke to Koni and they do not make shocks for the '89 year.
Hmmm ... I wonder what's so different in the suspensions between a 1989 E350 and a newer E350 such that the current Koni FSD shocks for E350 models wouldn't just bolt right onto a 1989 E350?
I'm not sure that what the Koni rep told you is true in an absolute sense. They might have been merely quoting their published literature on what E350 models their shocks have either actually been tried on or been dimensionally verified on for Ford E350 suspension drawings from later than 1989 models.
Unfortunately, the current Koni FSD shocks for the E350 just might have fit fine on your 1989.
