Hey guy I was wondering about how to tell if my car has an lsd in it buy looking at the vin or some other special feature on the car. The car is a 1996 se 240. And what gear ratio am I looking at in the rear end? I am dropping a zo6 vette motor into the car in two weeks. We did the math and the ls1 weighs 20-30 lbs. More than the stock motor and trans. I have the motor trans and every thing else. I am sure other people have done this swap. If any one has any info or pics of the ls1’s in 1995’s and up hook me up. I have some pars for sale for the 1995- and up cars so let me know. Thanks Jeffrey g
