Item Details

11" Rotor and 1978-Up GM Caliper to Early Ford Spindles

Notes

Installation Note:  If utilizing the later Ford 'Square Back' style spindle, it will require minimal modification (removal of approximately 1/8" of material from the spindle) to clearance the caliper bracket.  The early Ford style 'Round Back' spindle will not require this additional modification.  Due to the numerous types of bolt arm steering arms that can be utilized, installer provided steering arm bolts applicable to the specific steering arms may be required as provided by installer.
