I don't think any 7/9xx cars had a pollen filter.
Not sure even if the S/V90 had a pollen filter, both are still too early because as a general rule, pollen filters only seemed to arrive about 2000 ish. Yes, there were some cars that had them before then but also a lot that didn't get them until after, whether by addition to a revised heater box or because the car model was being facelifted and had a completely different heater box.
Martin have you got any pics of your conversion?
