After installing my short shifter from ebay using the items provided (which I werent happy with) I decided to change things up.
Firstly, the plastic coupling provided that goes around the ball down the bottom of the shifter was gay. I was easy to pull off and put on with your fingers (so if it's that easy, itll drop into your gearbox and do damage). So I went to Nissan Genuine parts and bought a brand new, original bit. this costed me $12. Its much thicker, slightly bigger, and tighter to get the ball in. THIS IS GOOD! I used a mallet to wack it on! then re installed it into my car, and YES! It was difficult to get into the gear box! yay! That means its nice and tight. Now I get NO play when in gear! It clicks in, and stays there!
Also the socket head bolts provided were too f**king small! I made a trip to Bunno's and got the same bolts but longer... and silver haha... I clamped the square bit on with EASE this time, and tightened it just enough, so it wasnt straining. Unlike the new longer bolts, I could only use 2 threads to tighten it, not smart at all. Locked up real tight (Thats why I only drove to work and back, then started working on the shifter again to refine it). I didnt want the vibration or anything like that to drive these bolts out.
Now the whining sound? I couldnt fit my original sound deadener boot around the gearbox and stick because there is a big square plate! So I just sat it there anyway, and put the rest of the boots over it.. I cant hear a sound now! It's probably due to the mixture of the new bolts, and plastic coupling.
Now, it clicks into gear, STAYS in gear, not tight and strenuous, and pretty much perfect.. I can't hear any whine as well
Thats my experience with the short shifter kit.
