62 Impala tach or something else?

[SuperNovaSS]

I recently posted this tach on Ebay:
Vintage Chevrolet Tach

I googled the part number and it came back as 62 Chevrolet. This made since since 1962 is printed right after the part number on the back of the tach. I know 61-62 Impalas came with a Sun tach from the factory. Could this tach have come in later 62's? I got this cup in a black painted Sun "pinch" cup. I was told it came out of a 62 Impala that the seller bought new and wrecked. Here is the link to the auction where I bought it:

62 S/S tach

I don't want to misrepresent this part. A Ebayer already wrote to me saying it was incorrct for a 62. What info is correct?


Thanks,

Jason
