This is the terminal block I'm ordering for my headlight mod coming up in the near future. It is just like the one on the passenger fender for the battery. VetteVet posted a picture of one earlier in this thread.
I like it because those plastic ears will make it unlikely to have an accidental short. I'm going to put it on the driver fender or driver side of radiator support, since that is close to my alternator.

It should be fine to stack 3 or 4 ring terminals on it to connect different things.
Also VetteVet has posted a picture on another thread that looked interesting
3 or 4 inches from my positive terminal I'm going to put a bolt and nut through the fender to act as a convenient ground terminal. I've seen other threads where people have done that to provide a nice clean connection for ground straps. Around the bolt hole the fender needs to be nice clean bare metal.
