The only place I know of is LC Engineering in the states who make performance parts for Hilux's (Tacoma's in the states) and Hiace Vans.
The short shifter isn't actually physically shorter, i.e. it will sit at the same height but you will only have to move it a small amount.
Their website is

They have more than you would ever want to buy for the lux, but at a big price :)
