It's all done!... My part, at least; the luthier will install a nut and the strings (+retainer) and set the bass up.
First, as I was removing the original bridge, I was quite surprised to find a hole to the pickup rout for grounding... I assume the Japanese bodies are drilled the same, and that the '62RIs have a copper strip installed in lieu of a wire like the '70-something-RIs. I didn't mind the copper strip at all, but as I bent/warped it the first time I checked the bridge pickup, I took it off and ran a wire in the hole. Screwed the bridge (a direct replacement, that was easy), and
voilà!
Then came the tuners... Always a tricky part for me (though I should know by now), as I always screw (haha) a screw or two. Actually, in that case, that was three. I'm pretty glad that those tuners need as much as four screws each, so I managed to install them; and three have a issing screw, but that can be added later, and it seems quite stable, I assume it won't be an issue.
Then, some bigger screws: the neck's. Unlike the tuners, I often find those easy to screw... Anyway, the neck was *very* easy to drill, plus I was eager to end the project. Funny enough, it was meant to be just a mod at first, and I ended with only four parts that are original: the body, the pickups, the neck plate and the tuners. But it was worth it...
I take her to the luthier tomorrow, hoping to get her back fast.
