5.7L V8 Naturally Aspirated LS1 (350hp).
Quick reference
C5 Corvettes are 2-seat vehicles; traditional LATCH lower anchors (ISOFIX bars) do not exist on this platform
Part numbers 88963004-88963006 require verification against 2002 GM EPC due to potential supersession in later service years
1997-2000 model years may not have factory mounting bosses for tether anchors; verify threaded inserts present before installation
Context
For the Chevrolet C5 Corvette platform (1997-2004), the LATCH/ISOFIX anchor set refers to the passenger-side child restraint tether anchor mounted to the rear bulkhead, as these two-seat sports cars lack rear seating. The primary anchor assembly (GM 88963004) bolts to the composite structure behind the passenger seat, accompanied by trim cover 88963005 or 88963006 depending on interior color. While lower LATCH anchors are absent due to the vehicle's 2-seat configuration, the top tether anchor provides compliance for forward-facing child seats in jurisdictions requiring passenger-seat child restraint provisions. When sourcing from junkyards, inspect 1997-2004 C5 coupes and convertibles alike, noting that Z06 models share identical mounting points. Check for stripped bulkhead inserts—the composite unibody requires specific torque values (typically 25-30 Nm) to prevent thread damage. Verify the 11588719 bolt kit is intact; if hardware is seized, drill out carefully to avoid damaging the captive nuts embedded in the rear wall.
