By chance the other week I bought some bits for my 185 from Jap Parts in Lambton NSW, the bloke there threw in the shifter Assembly (out of a ST184) which I noticed is different to the 185, turns out it has an insanely short throw, feels like a different car. If you are looking for a very simple and cheap way to get a shorter throw in your 185 this may be a way to go . I would say that it easily halves the throw in all directions and with brass bushings it feels very direct.
