When Exactly Did I Become a Citizen?

[perloquito]

I became a US-citizen sometime in the early eighties in Tampa, FL. Somehow, I cannot locate my naturalization certificate. Well, I never needed it after I got a US-passport. Now, I need the exact date of my naturalization in order to apply for social security benefits. Is there a way to find out the exact date of my naturalization?
Thank you very much.
