I must admit i set mine up in 4th, then i nip it up so it can still move a little and try the gearstick, if it feels a bit off i can just apply a bit more pressure to get it where i want then tighten the clamp properly.

Got a Ka linkage in mine, MUCH tighter feeling and closer together too. Downside is no neutral springs so it doesn't centre when you let go in neutral, though theres no real need for that.

Doing the Ka linkage in 4th helps me a lot, cause if you set it a bit far forward it can knock out of gear sometimes when you lift off in 3rd.
