When ordering the 3102-170, verify the companion flange bolt circle is 3.346" and the pilot bore is 1.772". The 0.410" bolt hole diameter is shared with several other flange yokes in this series—the distinguishing dimension here is the 3.346" bolt circle combined with the 2.671" CJ to flat. Confirm both dimensions against the companion flange and driveshaft assembly.

The 1310 series ears accept a 1310 series U-joint. The 2.671" CJ to flat is a longer offset than typical 1.6"–1.75" configurations in this series; account for this dimension when calculating the effective driveshaft length. Match the bolt circle (3.346"), pilot (1.772" M), and CJ to flat (2.671") to the application before ordering the 3102-170.
