who has silver a bodies?

was silver an option from the factory in the 60s and 70s?I hardly ever see a silver mopar at all,except the newer ones,but the ones i have seen were really sweet looking,mostly with red interiors ans red tail stripes.Id like to see some silver 70-72 darts
My first car was a 1966 Dodge Polara factory silver, I bought it from a local fireman who bought it new from the dealer. I don't think it was a special order car, but i could be wrong.
