It's probably alright. It looks like they have extended the lower part under the ball, so you may find you need to use some washers or spacers to lift the shifter cradle up a bit so the shifter arm won't foul the chassis. No big deal. You need to do the same with the TRD ones too (They come with the spacers).
Bear in mind as well, that the length of your shift knob will have an effect too. short spherical ones will mean less throw than a big long dildo.
You can also replace the rubber bushes where the shifter cables attach to the gearbox linkages with ball bearings for tighter shifts, and also replace the rubber shifter cradle mounts with metal ones too.
It just so happens that I have the bearings and aluminium mounts sitting here brand new and unused.PM me if you are interested....
