I think you are refering to this
how-to entry in my photo journal? We didn't measure the wheel spacing but it doesn't seem uncomfortable. It would be easy to knock out an inche or so of intrusion by simply cutting off a like amount from the top of the '59 sleeve and moving the dash mount screw holes up also. I have noticed photos of other cars with a tilt column conversion and custom steering wheel and adapter do stick way farther into the driver's chest. The stock '59 wheel doesn't stick out near as much. Regardless, the lap room is wonderful.
