Replacement 1963-1977 Corvette rear spring center mount bolts. Attaches rear spring to differential cover. 3 1/2" x 9/16", grade 8 bolts. For use with factory original 9-leaf rear spring. Car set.
Note: Due to the width of original, reproduction and replacement rear spring leaves and liners, Zip recommend verifying the number of spring leaves and spring width prior to installing. In addition - we do not recommend installing with an impact gun as both extra length and hard torque have the ability to crack the differential cover at installation. See Zip # BL-689 for 4" long rear spring center mount bolts used on current replacement rear leaf springs.
