Over-torquing mounting bolts used at the 1956-57 Corvette transmission mount (engine rear mount) can result in damage to the mounting. The two long bolts that extend downward through the mounting bracket as well as the two bolts from the mounting bracket to transmission extension, should be installed to a torque of 25-30 foot pounds.
