I'm wondering if this boss will fit up in our cars...I'm not sure of the difference between the steering setup on the cars this is supposed to fit, but I want the short hub so the steering wheel doesn't stick out too far and look stupid. Will a short boss by NRG for any other cars fit the maxima better???

I have this stering wheel:



and I want this boss:



It's offered in this auction:

NRG-NISSAN-STEERING-WHEEL-HUB-ADAPTOR-240SX-300ZX-S13

 

Good question.
I have a cheap ebay hub that isn't a shorty. It was listed for a 300z, but it worked and I'm pretty sure that the hubs for nissan is universal. Looking what you have I think it's possible that it's too short and the nut will hit the horn buttom. depends on the design of the wheel.

 

most nissan hubs are interchangeable.
