Thanks. Actually, the 1969 Impala was only offered with a 427 and you did get factory disc brakes with the car. That being said, you could order the engine, trans, seats, and disc brakes with a regular Impala. All you got extra for checking the SS option was a few badges and a different grill but it did mandate the engine/brakes. I don't know if you can really truly verify a 1969 SS from a regular Impala from records. Either way, I still enjoy the car and the SS designation is just something that would be nice to try and verify. My car has the correct grill and brakes and the body tag points to an SS build but it stops there. If I can nail down the original engine, I think it would be enough for me. Either way, the car will get a 427 next winter.
