For a custom or specialized rearend order please try and initially determine these three dimensions on your vehicle before calling a Currie Enterprises sales representative:
1. The Overall Width (Dimension A above): The overall width can best be determined by putting the tires under the car (make sure to allow a minimum of one inch clearance for the fender and the frame rails) and measure the distance between the wheel mounting surface on each wheel.
2. The Pinion Location: The pinion location in most cases will be centered; in some cases the housing is off center (a .94" pinion offset is typical, as in the diagram seen above). This allows clearance for brackets on very narrow rearends, so as to provide a platform for mounting upper control arm brackets for triangulated 4 link suspension.
3. The Wheel Lug Bolt Pattern: The lug bolt pattern is the number of studs (usually 5) and the diameter of the circle on which they are placed. The diameter is determined by measuring from the center of the axle to the center of one stud and doubling the measurement. See dimension BC in the Axle Dimensions Diagram directly below.
