Welcome to the place.
The official answer would be that you need to take the black wire from the new cord and run it to the fuse and then to the switch and then to one side of the power transformer primary winding. The white from the new cord should go directly to the other side of the primary winding.
When you do this, the cap that is connected to the power switch should be removed. And the green wire from the new cord should connect directly to the chassis via its' own nut and bolt. Additionally, the green wire must be longer in length than either the black or white wire.
You can do exactly what you outlined and just connect the white to where the original white was and the black where the original black was and ground the green wire, but it will not meet current standards.

No, in fact up until a few years ago what you propose was done as normal wiring in most commercial amps.
What I outlined is what current standards are and what must be done in all newly manufactured amps.
In the other thread Bart mentioned removing a resistor from the switch. It really is a capacitor, sometimes referred to as the death cap.
Edit:
I just remembered that the Kustom has a heat sensor in the ac primary circuit, so that would need to be included in the black lead wiring.

Yeah okay cool. Well I went ahead and replaced the black and white line where they originated. I removed the capacitor/death cap on every amp. They all powered up and work great. I didn't mess around with any heat sensor when I re-connected my black line. AAAAnd grounded my green end to the old death cap screw and nut. So far so good. should I be worried about that heat sensor?

I have a k200 a-2. 1967 or 68. I'm gonna buy a three prong hoover vacuum cleaner cord and switch out my old one. Would one of you more experienced kustom guys let me know if it's simply going to be a matter of removing the old black and white ends and replacing with the two new ones and placing a lug on the green ground end and attaching that to a screw and nut? If this works out for me I'm wanting to do the same with my other same era kustom heads. oh yeah, I had a beautiful photo of the inside of my amp for anyone to see but just read that I can't attach files. Bummer. It's my first post. Thanks.
