    If the shifter shaft is really long like the Spark's, you can easily hack off 4 or 5 inches like I did. A few minutes with a hack saw is all it takes, just make sure you figure out what is comfortable for you beforehand. My son's arms are a little shorter than mine so he cut off about an inch less.

    Those aftermarket knobs come with a set of plastic collars for a tight fit on the shaft, the three Allen head set screws keep it very secure. I was able to find a knob that looked very much like stock for less than $10 at the auto parts store. It only takes a few minutes to swap out any knob that suits one's fancy. I wouldn't worry about losing the threaded part of shaft, it's just a cheap and secure way for Mitsubishi to attach the stock knob.

    I've been thinking about a short shift too. I like the idea of shortening the top end of the shifter, which was something I was thinking about doing, but by adding a little bit of length to the bottom lever, I can definitely see the advantage. If you make it, I'll test it.

    I'm not going to cut anything off the top; I plan on using it for hill climbs and want the shift lever as close as possible to the wheel.
    BrisMJ makes a valid point about the shifter to wheel distance.

    So, the next question is who is interested in testing a prototype? I'll give a good price to the person I end up going with. Of course I'm going to require some pictures and help writing up a DIY install so others can easily install theirs. PM me if you are interested.
    Will do.

    So this week I finished up the short shifter modification and reassembled the shifter assembly.

    I started with this.





    Next, I had to remove the lower plastic ball joint piece because we'll be welding things and it will melt. To do this I made a small tool that straddled the metal shaft but was small enough to pop the plastic off.

    Then, I cut the shaft as shown.

    Now I busted out the welder, flipped the middle shaft section around and welded it back together.

    And then re-lubricated the plastic ball joint and put it back on.

    Last, but not least, I reassembled the shifter assembly.

    Nice!

    When are you going to get to test it out?

    Nice work, thanks for the detailed photos.

    Looks like white lithium grease. I'm curious to know if you fiddled any with the shift cables, and what are your impressions? I say this in the sense that other owners have addressed notchy shifting by lubricating the shift cables.

    I am going to meet up with local Mirage owner Spork to test the shifter out this weekend.

    Yep, the whole assembly is caked with lithium grease.

    I'm not sure about the shift cables. I've never driven a manual Mirage yet. This weekend will be the first time. The only Mirage I've driven was a CVT which shifted silky smooth. I'll keep your question in mind as we install it and see how different it feels in use.

    The top part above the ball is the height, the part below the ball effects throw. I think the height of the shifter is right (total length) which means to make it short through, extend the lower portion but keep the top same height. This is why honda cable trans short shifters are z shaped on top, they keep the stock height above the ball and extend the lower. In subarus, the aftermarket kit comes with an adjustable ball you can move up and down as it too is cable. Just my .02....
