Part 1:

Part number C2865-1EA0: I wanted to see if this shifter would fit since I used to have it on my Sentra SER back in the day. Unfortunately, it does not. The base of the knob is too small in diameter to clear the shifter’s top collar, so it can’t thread onto the shifter without an extender—the shortest one I could find is 2 inches. It’s possible to cut the extender to make it sit flush on the stick. That said, I’ll be selling this knob along with the extender if anyone wants to try making it fit.

Part 2:

I’m not sure of the part number for this shifter since I bought it used. It came off a 350Z with an OEM Nismo knob. I wanted to see if this one would fit better because its wider base diameter should allow it to clear the shifter’s top collar—and it does! The only “modification” I had to make was adding two 10mm washers to the OEM shifter where the knob threads on. This prevents it from threading down too far, which would interfere with the pull-up reverse lockout. This shifter sits much better, and I’m stoked I found it!
