Title: 1968 Z/28 GM PART NUMBER MUNCIE ID TAG
Post by: john302 on December 27, 2007, 07:34:37 PM
WHAT IS THE GM PART NUMBER ON THE LITTLE METAL TRANS TAG FOR 68 Z/28  WITH A M20 TRANS?  ALSO WHAT IS IT FOR A 68Z WITH A M21 ?   THE ASSEMBLY MANUAL SHOWS THE PART NUMBERS ,BUT IT IS CONFUSING.  ANY HELP OUT THERE?

John, there are a few different applications dependent on the rear axle ratio and with or without posi. What ratio are you looking at?

The M20 would be 3915079 for both the 3.73 and the 4.10

The M21 would be 3915085 for both the 3.73 and the 4.10
