New Dorman timing cover.  This is a cover with timing tab, and is a stock replacement cover for carbureted and TBI (Throttle Body Injection) engines.  This is different than the 85-92 TPI engines (the timing tab is different location).  This ONLY works with a factory GM balancer!  This includes the front crank seal and the cover to block gasket.   Fits the following:

82-92 305 Carbureted/TBI V8 Camaro
82-92 350 Carbureted/TBI Firebird/Trans Am
