9in. to 10in. Drum Conversion

Hello!

I have a 1964 Dodge Dart with the factory 9in. drums. The braking power, as is know, is poor at best. It's fine around my small town for now, but I'm moving to Long Island next fall where I need stop & go ability. Disks are way out of the price range I'm willing to work with. So my question is: how does one go about swapping from 9" drums to 10" drums (or 11 if thats possible)?

Thanks!
