I just discovered that the copper strap on the left rear of the engine is completely broken (separated) from the fitting that attaches to the head. Since truck runs fine and everything works like it should, is it safe to keep driving the truck until I get it repaired? The bolt in the head is going to be a bitch to remove.
I have seen lots of those ground straps either broken or missing. Ideally, it should be there. Just make a ground strap from 10 gauge wire and a couple of ring terminals. Find a bolt or stud that’s easily to reach on the intake manifold, problem solved. Just make sure to clean any dirt or paint from the surface for a good connection.
You will be fine enough. Our previous owners mechanic cut ours off many moons ago and left it to hang limp and sad. We are going to replace it here in a day or two just to make the ground path as good as possible.
