My 240z has a wicked boss that's flush with the end of the spline, thought I'd grab it and put it in the ute with my old flat Nardi drift wheel... 240z spline is bigger :(

I then ordered a boss kit from ebay... they sent one that was 1mm too big and about 100mm negative offset from the spline. Wish I knew how to cut a spline so I could make a positive offset one.

Have to wind the window down so my elbow can fit somewhere, haha.
