Would likely work but it doesn’t have the grounds if you’re concerned about that. I use Amazon because I get them in 2 days instead of a 5 days to a week like it seems to take from most places and it ships free with my prime.

I've used these with GREAT success. Bussed or individual, with or without relays, all your choice. I used a pair of them when doing the EFI on my '68 Charger and will be retrofitting it into the EFI setup on my '67 Charger as well.

I have this for part of my Coronet wiring. Same as above, but already populated and wired. Nice that it is totally sealed.
Only issue is the relays are bused together so they all have to be triggered the same polarity.

I've used Blue Sea blocks on several race car wiring jobs. They come in several configurations including split power buss (for switched and un-switched power), with or without a ground buss and blade or glass style fuses. They are high quality and I like their use of screw terminals as opposed to push-on style connectors.

thanks very helpful. They looked like they ate built good but hard to tell so your feedback is very helpfull. Not sire what a ground bus buys ya in this application but the unit I posted actually had a wiring diagram. Its the only unit that had a wiring diagram that clearly shows both switched and primary unswitched lines. This is the closest think to the stock set up electricaly.

Here is a link for the model 5032. It has two power busses for switched and un-switched power. It's simpler than the 5035/5037 model because the two independent power busses are built in which eliminates the need for an external power buss. It also eliminates the need for individual power feed wires per fuse. The 5032 also has 6 circuits per buss. The ground buss is handy for any add-on devices such as after market radios, gauges or lights, etc.

The original diagram shows a marine setup with two batteries. I have modified the diagram for one battery.

Now that I've said all that, let me throw you a curve ball. If you are only interested in replacing the original fuse block, locating/hiding a non-stock fuse panel for easy accessibility may be an issue. Rewiring all the ends (in tight quarters) and having all existing power wires long enough without additional splicing would make you the luckiest man on earth. This is a big job and like every project, whatever you estimate the cost to be, double or triple it. I know they're expensive but a deeper dive into an OEM style harness with parts might be better in the long run but that's just my opinion. Keep these old Mopars going, good luck and please keep us informed.
