Very nice Ricardo, making good progress.
FWIW, following on your comment made somewhere about two different kinds of two-row pulleys, I have a water pump pulley that has a wide and narrow groove that I don't need. Looking at the one currently on my truck, it has two wide grooves. On the wide-narrow pulley, it looks like the outer row (closer to the rad) is the narrow one, which would align with the alternator on my '77. There would have to be a crank pulley that matches though, so don't know what use it is. I'm trying to get rid of it now that I know I don't need it.
It feels nice to have wiring all fixed up nice so it's not a rat nest eh!?
