2. What you need to Know
There is no parts book that will identify the steering gear on any given vehicle.
The part number however is stamped on each gear. This presentation will show you how to locate that part number.
Due to road tar, paint, grease and dirt it can be difficult to see the number.
Finding the number on the gear is the only means to insure you order the correct unit.

3. Sheppard Numbers Are easier to locate than the Ross numbers
They are also easier to read
They are usually in the same location throughout a given series of gear
The hand stenciled number will consist of between two and five letters and/or numbers
The stencil number may also include a manufactures date code which is of no importance in identifying the gear part number
