Paying down debt vs 403b investing

I am 63 and will retire at 66-2/3. I have significant credit card debt ($20,000), student loan debts ($40,000), mortgage and car loan. I have only $50,000 in a 403b. I will retire with two pensions and social security, about $4000/month income. Current annual income is $82,000. Is it better to pay down my debt to retire with little or none, or put as much money as possible into my 403b
