OD-C1 wiper help needed

[fiddlybits]

I found all the pieces and parts and got it all together and working.
Mount it on the windshield frame and life is good.... almost...

The stupid power terminal does not come all the way through the windshield frame. How is power hooked up to this thing?? I have the connector on the end of the wire that snaps on to the post (terminal) but the post is only flush with the inside of the windshield frame.

Is there an extension? Is there more than one length post? (I don't find anything in the standards that says there is anything more and the drawing shows the post the same length as I have.

Anyone have a photo of wiper from inside the cab? This would be for the OD that has the offset shafts.

Thanks
