I know this topic has come up a number of times in the past: switching out the black VW wipers arms for something a bit more period correct. (Rather than painting them silver)

I received a notification in my email Friday (as I’m sure many of you did) in reference to a sale at Sierra Madre for wipers. 

Please see attachments.

Ryan, I believe @TRP and @*LongFella have some experience installing the “correct” wiper arms onto our cars. The ones @*LongFella installed are the ones available from Sierra Madre now. The ones @TRP recommends are not available. Could either one of you weigh as as to what is required to install the wiper arms?  Any grinding or drilling, or is it plug and play with our VS wiper assemblies?

VW wiper shafts used at least 2 types of wiper arm attachment.  Early ones (pre-67/68) were hidden from view and a small bolt was tightened to grip post (I think 356 used the same concept but not sure size of the post was same).  Later VW (68 up) used the big ~13-14 MM visible cap nut.  That was used on later Porsche (even the last couple 356 models) but of course, the arm was much longer.

No idea what make/year wiper motors VS used - mine is CMC so wiper motor is from donor so from a 71 bug.

Thanks so much for the "heads up", Kevin. And for the tips regarding what to buy, Longfella. You guys are the bestest.

@Ryan in NorCal  I don't know if you ordered yet, but the discount code did not apply to the wiper arm set.  However, it did apply to the Jorg wiper arms:


My cart total with the two wiper arms and blades is: $65.89

My set is on the way, so now I can hang out with the cool kids.

Thanks for the tip on how to get the discount. $65.89+ $10.45 shipping to 61550, so my "all in" was 76 bucks and change, which is a lot for wipers.

But you can't put a price on cool. Buy once, cry once.

I was also too excited to let them sit in the box, and installed the new wipers and wiper arms yesterday. 

It is an simple procedure. 

1. Remove old wiper arms (mine had a cap on the top that needed to be removed first to expose what I believe is a 10mm nut. Take off nut. I put a number of microfiber rags down surrounding the arm. Using a regular screwdriver I gently pried the arm off the assembly). 

2. Locate position of new wiper arms and blades on windshield,

3. Use a small file to file a bit of a flat spot on the wiper threaded post,

4. Install new arms  



I still need to put the slight bend in the arms, similar to the restoration photos I snagged off Wilhoit’s website. (Attached)

Ryan, I was a bit alarmed as well when installing. Yes, it wasn’t exactly the plug and play I had hoped, but with a little modification, I think you can get the desired look.  (Which always seems to be the case with these cars)

Which is why I immediately turned to Wilhoit to see how their restorations appear. 

It appears on their restorations, the arms sit high exposing more distance between the body and bottom of wiper arm. 

I zoomed in to the photos I attached earlier to highlight this distance. 

I filed a flat spot due to @TRP comment about the arms flying off. At least I thought he said arms. I figured a flat spot would be a little better in terms of grip.

Don'r over think this. Pop off the plastic nut cover, 10mm nut gets removed, I gripped and ripped the old ww off the spline, use a round screwdriver to tilt out the small block on the new ww arm, line it up and tighten the bolt. If you want file a flat spot on the ww post spline before you put the new arm on. Make sure the blade portion is set back about a half inch from the end and tighten the blade to the arm. Turn on the ww and check for clearance.

I suppose if you don't like the way the arm sits proud of the body, which isn't much, you could file the post a little shorter so the arm sits lower. Just don't overdo it or the arm could contact the body.

Ryan in NorCal posted:

Kevin, would you mind sharing a closeup of installation? Blade up and down?

So I completely ignored your request Ryan. For two reasons. One, @*LongFella had photos above. (And, frankly, between my work and his, I’d go with his all day). 

The second reason was, given the bar this group has created, I was embarrassed to show close ups. When I painted my VW wiper arms and blades, I removed the cone grommets and painted them the same silver. When I was attempting to remove the VW wiper arms last week, I chipped the paint on the cone grommet. Therefore I waited until the new cone grommets arrived before I snapped photos. 

I did take the Speedster up to Napa today, and the wiper arms did not come loose at 80mph. 


***PLEASE NOTE, and this is huge*****

for all those going from VW wiper arms to original style wiper arms please be careful the first time you open your frunk. The original style wiper arms stick out further than the VW ones. You will hit them.

@Kevin - Bay Area Initially I thought yours looked a little lower than mine as well but now that I'm at my MAC looking at large photos instead of my phone, it looks like yours are sitting at about the same height as mine. I originally posted that I thought mine seemed to be a little proud of the hood but they're the same.

The new wipers definitely sit higher. I suppose there are two options. Lower the height of the wiper stud or drill a hole in the attachment point and see if the stud will sit in the recess.

Before I cut the spindle or drill out the back of the attachment point doers anyone have any other suggestions.

@TRP How are yours sitting and what did you do????

So after I got back from my drive yesterday I took a few minutes to look at the new wiper assembly. I couldn't drill a hole in the attachment arm because there wasn't any space above the attachment arm where the top of the spindle would sit. Once the wiper arm is pushed forward so the blade rests on the window the top of the attachment arm is resting against the bottom of the wiper arm cover.

So the next option was to re-profile the spindle. I used a grinder to grind down the spindle shorter. I fit the wiper arm onto the spindle but it still wasn't low enough. The bottom of the attachment arm was now hitting the top of the splined portion of the spindle and that is tapered. I didn't want to enlarge the hole in the attachment arm so I got my Dremel and small grinding wheel so i could reshape the splined part. 

I found it best to attach the small grinding wheel with the abrasive face of the wheel facing back toward the Dremel. I reshaped the flared spindle and reattached the wipers. They sit much lower now and the open trunk clears with plenty of room.

I’ve looked at numerous photos of Speedsters as it relates to wipers. For one, our VW setup will never be an exact match if that’s the goal. They are different. That said, in every photo I’ve seen, there’s definitely a distance where the spindle is seen.  I’ve also seen a variety of wiper blade placements as it relates to its resting position on the windscreen. Some are angled on the windscreen, some rest flush against the rubber seal at the bottom, and even one where it was located off the glass below the rubber seal.

Seeing the spindle doesn’t bother me, personally. I just enjoy the Porsche wiper arm over the black VW arm.  I guess it becomes a “pick your battles” scenario.  

As it relates to the install, as with everything I have purchased for this car, nothing has ever been a simple plug and play for me. Even the simple rubber gaskets around the horn grills. I had to drill my own holes in the gasket. As the holes that came pre drilled (on the gasket) were at the 6/12 position and my holes are at the 3/9 position.
