I just finished with my new shift knob. Drilled it out the same dia. as the shifter but the shaft is splined. If it was just a flat piece, like the stock unit I could drive it on with a mallet but it is detailed and a little delicate, not to mention the paint job. What is the best way to get it on? Should I ream it out and them use epoxy to hold it in place. The way it is now, it will not be loose once it is in place and may never get off. (Kind of like my ex!) Ouch!
