How many circuits do you need ? and what anticipated amperage per circuit ? If each circuit was good for 30 amps I can always fuse down. 4 relays maybe 6 or more circuits. Modernizing my 65 and would prefer to put new loads on a new system rather than tax the existing.

Hit the junkyard. Look under the hoods of newer vehicles, I've pirated a few for my uses. I like the ones under the hood of 89-92 rangers. I used one to delete all my fusible links on my 85 D150 by running everything that used to have a fusible link in it thru the fuse box instead. We did the same on my son's ramcharger when we deleted the TBI and went 4bbl, that one came from a 98 zx2.(escort) Thanks for the reply. Those days are gone here in ct . Any yards remove the parts for you . Also don’t want a bunch of splices . Want to be able to go right to the fuse or relay. The key thing I’m looking for is something with a common positive bus bar so all fuses are powered instead of having to feed each one from a positive lug or bar

I source the components and do systems according to what it is and how much stuff there is. Typically I like to locate relays near the component it is controlling. Separate components, as opposed to all-in-one assemblies, allows for quick repair/replacement in the field in the event of a failure.
Littlelfuse/Bussmann makes nice stuff and usually have what I need. Relays and other parts are from notChina places as well.
If the results don't match the theory, change the theory.

AndyF mentioned the MSD Relays some time ago. I took a look back then and they have a nice form factor and some pretty interesting features. Holley just sent me an email saying that they have added some part #s and some of the MSD Relays are on sale (Holley owns MSD). Check out: https://www.holley.com/products/electrical/wiring_and_relays/ There are lower priced relays with less functionality and higher priced solid-state relays. See: https://www.holley.com/products/electrical/wiring_and_relays/parts/7566-4 The lower priced relays do NOT have a common input power bus. The more pricy solid-state relays like this high-current part: https://www.holley.com/products/electrical/wiring_and_relays/parts/7564-HC have a single power input bus. The solid-state relays are cool because they switch fast enough to take a PWM (Pulse Width Modulation) signal on the relay control circuit and produce a PWM output for the load side of the relay. So if you need the really fast switching of a solid-state relay, these parts are a good option. Read the .pdf instructions at the link for each part# to get more detail. Full disclosure - I haven't purchased one of these yet but I have several of these part #s on my Summit wish list.

Leash Electronics has a lot of neat stuff and can custom make you what you need.

The key thing I’m looking for is something with a common positive bus bar so all fuses are powered instead of having to feed each one from a positive lug or bar That's how most factory stock ones are, some are always hot, others are hot w/ the key. I cut my fuse box about 10" away from the box itself, so I had plenty of lead to work with. I then butt connected them ( bare un insulated crimps) then soldered them and heat shrunk every splice with the " good" heat shrink, the heavier walled stuff with the built in adhesive that oozes out as the heat is applied and the tubing shrinks

heavy wall heat shrink with the adhesive is marine grade stuff. i use that a lot. as always, there are many places to obtain this from, and some are better than others. shop around and compare brands at different places. some places add a markup to the [same] product just because you purchase from their "name".

You might be looking at the Bussman 15300 series fuse/relay boxes. They come in different configurations: https://www.eaton.com/us/en-us/catalog/emobility/series-15300-rear-terminal-mini-fuse-relay.htmlPages 48-49 of the catalog: https://www.eaton.com/content/dam/eaton/products/emobility/CPCD_Transportation_Catalog.pdfNormally 1530(3 or 5) - 2 is the 5 Micro relay and 10 fuse base. I believe it has one positive buss to all the fuses, and another buss for the relay grounds (when triggered on the high side.) If using non-polarized relays, the relay bus could be connected to power through one of the fuses, and triggered on the low side. I'm not sure why Amazon is $90? I actually ordered that one from Amazon on Aug 11, 2020 and it was $39.02 back then. Waytek is $42.85 for the 15305 (metric screws) version -2-2-4 I noticed you can get them pre-wired with the fuses and relays on E-Bay, but they are expensive, $230: https://www.ebay.com/itm/132449489662
