Specifications
- Part Number: 3-70-58X
- Bolt Length: 1.5"

- Center to Center: 1.66"
- Bolt Torque: 32 ft-lb
- Application: GM applications
When installing the 3-70-58X, torque the .312-24 bolts to 32 ft-lb. The longer 1.820" total bolt length (including head) is the defining characteristic of this kit — standard strap bolts for the same thread size are shorter. This extended length is required by specific GM yoke designs where the strap saddle depth necessitates the additional bolt shank length.
The 1.66" center-to-center dimension of the 3-70-58X is very close to the 3570-20 (1.67") used on 1350 series joints — confirm the exact GM application and required total bolt length before ordering to avoid substituting with the standard-length variant. Do not reuse strap bolts after removal.
