-====== Oil Pump Drive Gears ======
+====== 1957-1967 Oil Pump Drive Gear ======
+The 57-76 pinion shaft has 4 external splines and one is longer than the other three. \\
+The oil pump drive gear has 4 internal splines that match to the pinion shaft with one longer recess between them and is a slip fit over the shaft. \\
+The drive gear slides onto the pinion shaft one way (only) with a timing mark in the front over the wider recess. \\
+You can't install the drive gear in any 360° position where it will fit on the shaft and it's timing mark does not line up with the pinion gear timing mark. \\
+The timing mark on the front of the drive gear isn't used to time anything but may simply be there to distinguish that to be the front of the gear. \\
