Ken,

There is good news and bad news.

The bad news is that all of them are leaky. New, unused, pristine, it does 
not matter. Chemistry did it. It's not your fault. It's not Sprague's 
fault.  They will not work well.

The good news it that you can sell them on eBay for money. Real  money. 
Just do it. Then buy new good last forever nice working capacitors from 
wherever you can.  It does not matter what kind you buy. Jut do it. They 
will make your radio happy.
