I believe this to be manual mirror P/N #2802710 except this number appears nowhere on the part. There is one number on the base P/N #2802699. Correct me if I'm wrong but the assembly as a whole is 2802710 and the base as a sub assembly is 2802699? This mirror has gasket P/N #2802303

Was this mirror used on 1968-70 B-Bodies?
