6v cube or Bosch style relays are not as easily found as the 12v versions but Amazon apparently stocks them now and at a decent price. There are also individual sockets available for the relays or in some cases the relay could be put in a modern style fuse box -- if you wanted to use modern ATC or ATO automotive style blade fuses.

If your accessory already has an inline fuse then there would be no need for another fuse and you would just need a terminal block powered by the relay. A terminal block would eliminate all the accessory wires trying to go back on a single terminal at the headlight or the ign switch.

If you did need a fuse block but want to stay with the the old style glass fuses then YnZ has a glass fuse holder capable of holding 6 fuses with inputs that could all be connected by a single buss bar connection to the relay but at over $50 it is pricy. The glass fuse holder selection that Amazon carries is limited but they do have a couple that would work. Those holders do not have a buss bar so would need a bit more work with connections to power them all simultaneously from the relay.

The glass fuse holders of today are for the consistent length AGC style fuses so some of the lower amperage SFE fuses that Packard used which came in different lengths sized for specific amps would need to change to a consistent length type fuse if you did not already have or wanted to change an inline holder.

If you want to do something with a relay or fuse holder/terminal block several of us could come up with a wire diagram and maybe a parts recommendation for you.
