rear-end
all ls1 and lt1 fbody's have 7.5" 10 bolt rear end. the actual gear ratio is different for every car. i believe sll M6 SS have 3.42 gears. just look for a code GU6 if you find that code in your glovebox or drivers side door jamb you have 3.42.
BTW this is the LT1 forum 93-97, try asking questions about your car in the LS1 forum 98-02, you will find lots more help over there
hope this helps
