We haven't been manufacturing a lot of stuff in this country for a long time. What passes for 10AWG 12AWG etc is likely mm˛ now. Just like plywood and dimensional lumber is actually metric now too.
The fuse panel is mostly filled with Pak Con terminals.
I've never purchased bussed Pak Con terminals. I know they still come in the Pak Con ATC/ATO "add on" fuse blocks like the units Polaris uses on their ATV and UTV. The Pak Con bussed fuse blocks, like the one pictured below, are around $10 so you might want to do some digging. I bet the bussed terminals can be found at least in four and maybe five and six terminal strips.
You can buy the individual Pak Con fuse panel terminals. I'd be sorely tempted to solder the individual terminals to a strip of copper thereby manufacturing my own bussed terminals.
Since terminals on a reel to load in a machine are bussed together on a plated or just plain brass or copper strip... you could buy some "reel" packaged terminals from Mouser Electronics and verify if the reel spacing is the same as the fuse panel spacing. I bet that's why Delphi Electronics chose the fuse spacing they used in those fuse panels. Why buy special terminals when you can buy something already in circulation.
