Yeah it's just for the la plant because my 68 is a la car as well and has that style of sequence. Doesn't mean a thing to the history of what the car is.

 

No, nothing to match it to the car. As I stated earlier, somebody could have changed that long ago, as has been done by a number of owners over the years. Also keep in mind that the 12 bolt rearend was optional for the SS model. So just as the presence of a 12 bolt doesn't automatically mean the car is an SS, the lack of a 12 bolt does not mean one couldn't be an SS. You know when your car was assembled, so see if the dates on the rearend fall within a reasonable amount of time before the car's build date. Still, all you will have is a suspicion and nothing more. If you're looking for cold hard facts to prove the car was an SS, you have none. That went away with the engine.

 

Thank you!

 

If the dates correlate correctly then you have one of three things with the 12 bolt. The 12 bolt was standard on all ss and z28 cars in 68. 69 is the only time a 10 bolt could come in a ss car due to the engine and transmission combo. The other thing is the l30/m20 cars. They also received 12 bolts in 68. Another thing to look for is check on the outside of the driver side of the subframe for a proportioning valve. In 68 only the 12 bolt cars had it. It could have been removed over the years but if the lines are original than it will help identify if a 12 bolt factory or not.
