Wiper shaft identification

I'm need to get wiper arms but have a small quandry. I have threaded wiper shafts, which tells me they are either 70-72 or 73-77. How do I identify the right year so I can get the right arms, nuts and caps?

Why not drive your car to an auto parts store, remove one and take it in for a comparison.

I think you are thinking about the wiper arm. I'm talking about the shaft the arm attaches to. I can't drive the car to the parts shop because I'm building a VS kit and, although it's close, the engine isn't running yet. I live east of Dallas, and the nearest VW parts shop is more than an hour away, so it's easier to order by internet or catalog. I need to identify the year of the shaft so I can order the correct wiper arms to fit them. I'm hoping one of the members knows how to identify the year. Otherwise, I'll take the shaft off the car, hop in the truck and go for a drive.

Mid America Motorworks has all of the wiper shafts available, catalog page # 17, lower right.

Get in touch with them: 1-800-500-1500 or www.mamotorworks.com and talk it through with someone there. They're very helpful and want your business, you ought to have pretty good luck with what you need.

Alan,

I finally got a picture to upload. If you can't identify the year, I'll take TC's advice and call Mid America.

Thanks for the help.

They look just like the posts on mine and other VW's I have owned.
