the first 3 numbers in the serial number will tell you, I don't know what the numbers are for a 63 impala but I have a 67 chevelle ss and the first 3 numbers are 138 for a ss model.
The 1963 Impala SS came with 8.00-14 as an upgrade from the standard 7.75-14
The 1963 and 1964 Impala SS models differ primarily in design and features. The 1964 Impala introduced a more refined front grille and rear tail lights, while the 1963 featured a more angular design. Additionally, the 1964 model offered a wider range of engine options and improvements in trim and interior comfort. The Impala SS (Super Sport) designation in both years signifies a performance-oriented version, but the 1964 SS had enhancements such as bucket seats and a floor shifter, setting it apart from the standard Impala.
should be on the drivers door pillar post
a true supersport should be full of ss"badges" or take your vin# to a gm dealer they can run the # and it will tell you

A 1963 Chevy Impala SS is worth anywhere between $3,000 on the low end and over $100,000 for those in top condition. The value varies greatly based on the number of original components and how well it has been maintained.

Look under the shifter in the console area
I don't have a 63 impala but if I did and there were ss badges on it I would want to know for sure if it was real, you can check the serial # on the vin to be sure.
1996 impala ss
No, the 94-96 Impala did NOT come from the factory with a sunroof option. However, there are many Impala's out there that had sunroofs installed by the dealership that they came from when they were new. So, it is possible to find a 94-96 Impala SS with a sunroof.
