Leaking Wiper arms...need grommets?

Need to get a pair of these. I have traced the last inside leak to these, I think. They are not on the car at all now. Are these these a standard size that I can p/u at any local HW store? Or is my best best the dealership. There is no mention of these or diameters that I can find in any of my books.

Also, I checked the archives so all kittens should be safe

of BMW/years. $2 ea. (or less). But if you've got water coming inside the car, replacing the windshield wiper post washers isn't going to fix it. Any water coming in through the windshield wiper posts goes right into the air plenum trough and should go out the three drip tubes in the bottom of the trough. Sounds like you've got other problems.

you can find a similar grommet at any hardware store. You may need to remove a bit of rubber from the ID. This is what I did and it works great. Each grommet was less than a buck.

I believe these grommets allow water into the cavity where the wiper motor assembly is located. This area is already open to the elements. You probably have a leaky heater box seal or a leaky windshield. -j

Know it's not the heater box, I just rebuilt it a week ago and it was leaking before and now after. But what I did find was a puddle of water under the dash and have only been able to trace it to these holes. What I assume is happening, is that the water is catching the lip of the metal and running towards the A post therefore leaving water on the metal dash underneath. In turn it then runs down the sidewall carpet to the floow. Window seal doesn't seem to be the problem from what I can tell. It is fairly new. What size were your grommets. Thanks

upon further exam.Ssince I have big hands, I thought there was a metal lip under there allowing water to travel. But it turns out not to be the case as you stated. Thanks. I will get the grommets, but continue in my search for the culprit.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
