This is a new set of black shift knobs for the M38 and M38A1 and early CJ5. This kit is is for the push on style main shift knob. This little kit includes the large shift knob which is simply a push on knob and two smaller screw on knobs for the transfer case. They have the brass threaded inserts and are 5/16 threaded. It will be pretty obvious if your transmission shift stick requires the push on style. They fit the original shift levers.
NOTE: Please check your application before ordering. These will fit many other models of jeeps but they need to meet the requirements listed above.
