    Exactly what I needed!!!!

    I could not find the original wiper axles with good knurl and this Lil piece rite here saved the originality on my 1966 chevy P10. With a Lil machining we good to wipe off another 50 years.

    Cheaply made but useable

    It works to convert 1/4" wiper motor shaft to a 1/2" . The set screw is too long so you either have to grind the point off the set screw (losing its ability to bite into the shaft) or grind a rather large flat on the wiper motor shaft. Don't forget to add a little blue loctite to the set screw so it doesn't loosen.

    I replaced the wiper knurls on my 41 Ford coupe. These fit great and are direct replacements - great product that is hard to find - thank you Speedway for having them in stock.

    Unfortunately this "universal" fit item did not work for the wipers on my 55 F100. But it was inexpensive enough to take a gamble on and I'm sure I'll need it on another project.

    Fit the shaft & allowed me to mount my wipers on a 1954 chevy truck. Had to file set screw down to get wiper arm over it. I would buy again.

    My 1965 Volvo amazon has 1/4" drive post for mounting the bushings. What does the bottom or other side look like? Is it like what is shown i n this image or is there a recess for a 3/8 or so washer/seal ring? I like the set screw feature and would like to use these. Thanks
