Customer Rating: Summary: Where's the jam nut? Comment: You really can't mess up a shift knob, no moving parts. This is a high quality knob that looks great on my Artic White Corvette. However, there was no jam nut included in the package. You need this nut as the stock knob doesn't use one. My knob was new, but came from the Amazon returns center. Maybe that explains the missing jam nut.
