Alternator Mounting Bracket - 2002 Corvette C5 LS1

The Chevrolet C5 Corvette alternator mounting bracket (primary part 10260635) is a platform-specific cast aluminum component that positions the alternator on the passenger side cylinder head, distinct from F-body applications despite sharing the LS1 architecture. When sourcing from salvage yards, prioritize locating the raised casting number 10260635 rather than relying on service part numbers due to GM's extensive supersession history. This component fits all 1997-2004 model years including the high-output Z06, though interchange with Camaro or Firebird is impossible due to Corvette-specific accessory drive geometry. Critical inspection points include the lower mounting ear for fatigue cracks caused by over-tightened alternator bolts, and verification that the M8 adjustment slot threads remain intact. During installation, apply medium-strength thread locker to the three cylinder head bolts and torque to 37 Nm (27 ft-lb); additionally, clean the ground strap connection at the rear mounting point to prevent erratic voltage output. Always replace the complementary adjuster arm (check for casting 12551323) as a pair if either component shows wear.
