This is a very high quality and very correct shift knob for the WWII jeeps. This is 100% correct for both the transmission and transfer case on the MB and GPW. These are also correct for just the transfer case on the CJ2A, Cj3A, Cj3B, M38 and M38A1. These have the correct grip ring and made of hard rubber and not plastic. The brass insert is 5/16 - 24  thread.  This sale is for one knob.  QTM Parts
