Holy crap!!?? There was one of those poles on the Auto GA2 City I sold a few years ago (got $2400 for the car which I thought was fantastic). Should'a taken the pole out and advertised it on US ebay.
Just as a side note, while I was looking for some info for my DA9 I came across this site for manuals (it mentions the 86-89 Aerodecks) http://www.pauldesign.ru/honda/shopmanual.html
