you'll want to replace those two little bushings on either side of the shifter bottom.

 

Alot of people do the short-shifter upgrade at the same time.

 

so if i was to do the short shifter upgrade..is the onde from courtesy a good option?

 

There is this guy. His name is Tim on zcar.com and he uses the name SilverTwin(OH) A lot of people contact him as he makes the short shifters for a Z and he has a good rep for great quality. It's actually a modified stock shifter. The modifications reduce the overall height by 1.25" and the pivot point is relocated to reduce the throw by 35-40%.

Send him your core though. I think his price is way better than anywhere.
