Recently purchased the Ali express short shifter for my 240 and thought I'd share my findings

Overall the quality seems pretty good and I'm happy with it. I measured before and after and my throw from 1st to 2nd has been shortened from 150mm to 100mm. There's also a lot less slop in the stick, I did do the shifter cage bushings at the same time so that will also help.
A few people had said I may need to modify the shifter to get it to fit. Personally mine went in with little drama. The smaller bushing on the shifter linkage fork where a little tight but not impossible to fit.
I've wired the overdrive to a switch on the dash and will see how this goes. I'm sure there's a clever way to get it on the knob again but I'm not concerned at the moment.
A few things that could be better in my opinion. Because it's not bent like the factory shifter when it's in 1st or 3rd it sits very close to the dash and is right at the end of my arms reach.
Also when in neutral it isn't vertical, this could be my car more than the shifter itself but it bugs me.
And finally the factory shifter boot doesn't seal nicely around the shifter, I'm yet to see if this makes much difference to road noise but we'll see.
Overall these are pretty nit picky and if you want a decent cheap shifter I'd give this a go.
