Current knob, 2" ball with 5-sp pattern, using "thin" hex jam nut. The photo makes the nut stand out more against the chrome than it does in reality. A polished SS nut (or chrome) would be a better match. The nut is no problem with "feel" at all; my fingers get nowhere near it in normal driving. The looks are off, though - a little heavy and industrial looking to me.
Current knob with thin chrome beauty jam nut, the look I'm going for. This nut has a bad tap; I may try again with better clamping on the nut.
OEM knob, looks great, will go on for show, but has 4-sp pattern and is too small and angular for my hand's comfort.
