great!, is there a proper boss for this swap!, i would take that any day!, i'm looking to swap a 120y steering wheel for a 240k or 240z steering wheel with a larger spline, is there a boss that does not have the 6 bolt new wheel setup? it cant be this complicated, either a new spline (which i'm not sure will bolt up to the steering column... (question: does the splined part at the top of the steering column bolt to the column itself or is it all one piece?) and if it does will it be adaptable with the 120y column??) or a reducer which will allow these two to adapt to each other... its always a safety issue, just like every other adjustment i have made to this vehicle, but i'm talking 2 or 3 mm here, everything else is a perfect match.. so if a reducer or welding is possible i dont need to change out steering wheels every month...i just need to know a boss kit which will work with this spline to spline swap or a remedy for column attachment of a 120y column to a 240z spline end piece...whoff....
