Replacement for fuse block terminal

Thanks for the all thoughts and responses. I’ll give eBay a look. I did try and search about a month ago when I was working on this but came up empty handed. Been too busy to think about it since. Ill look again since something may have come up.

The issue is with the wire/crimp connection to the terminal. I’ll try and post a better picture of that here. A spare fuse box may help if it came with long enough pigtails to splice into the original wiring

I agree. The condition of that wire and wire crimp render it unfit. Looks like the feed wire for switched hot (diagram designates it something like Q2 12 gage Black).

You may find it neccesary to splice in more wire even if you find the buss kit.
Best thing for hunting this stuff is the part number from the '74 Parts Book, assuming there is one for just the buss.
Its around '73 when the A-body fuse boxes get another fuse cavity. The earlier boxes don't have a 3 holder buss, however other car lines and brands may have.
