here's a quick sketch of what you can do.

The idea of using modern fuses such as the Maxi-fuse instead of links is good for the mentioned reasons. A junction block keeps the mess of cables away from the starter large bolt, which was used as a handy junction point.

Since you are not using the ammeter, you can use the existing brown wire from the alt to the junction block, and the yellow from the block, thru the fuse, to the main feed to the car.

The two fuses protect against an alt cable short and a short on the main feed to the car. As always, there's no fusible protection from the bat to the starter; that would need a 400+ A fuse.
