What is wrong with the ones you currently have? If they aren't bad DO NOT mess with them. Kustom amps do not like to be messed with and have parts changed that don't need to be. If you have a blown resistor, repair that one and be done. If you have bad filter caps change them and test and be done. They are not like a tube amps that you just do a whole sale overhaul to. They don't like that type of fiddling with. I have late 60's heads that have never been touched and still rip. They were made with the best parts money could buy.

To answer your question, the main filter caps are the two large cans that you described. Each one has two screw terminals on the top where the wiring connects them to the circuit.

Call up Mouser electronics(800 346 6873) and tell the sales person you need a computer grade screw type terminal can cap that size wise is 2.5" in diameter and anywhere from 3.125" to 4.125" tall.
The shorter height size(3.125") will keep you from untwisting the wires that connect to them for more lenght.
It should be 10,000 uf and have a voltage rating of 50 volts minimum, but 75 to 100 will make for longer life.
