I'm having difficulty finding a source for a replacement rear wiper arm for my FL Combi.  Most that I've found incorporate the washer in the hub of the arm (my washer is mounted at the top of the tailgate).  I've had 2 delivered and they both have the hub that attaches to the spindle set too high.  The net result is that the arm by the hub fouls on the glass of the rear window. At the moment my only solution is to cut the hub off of one of the new ones and glue it under the hub of the other (with a bit of drilling so the retaining nut fits).  I'm obviously putting the wrong incantation into the web search engines, does anyone have the OEM part no which I can use to get the part I need?  Thanks.

The part number for the wiper arm for a 2011 Octy 2 combi/estate is 1Z9955707.  Parts catalogue entry HERE.

Thanks, I'll give that a go.

Yeah. They're a very rare thing in the aftermarket world. You'll probably have to buy genuine new or a second hand part but the spring will probably have stretched and clamp down pressure will be down a bit on a second hand item. May not worry you that much.
