In that case, if it was me I would try it with 2 fixing screws and fit the E and G strings to make sure the scale length/ intonation works, if it does you know the A and D will be be okay , if that makes sense 🙂
I’ve just looked at my US jazz and it’s hard to tell with the strings in the hole but it looks like the bridge is slightly forward of the holes, maybe to give it a slight break angle, I’m sure someone more qualified will be along soon 🙂
Project for someone maybe

OBBM made all of mine but he’s retired now, but there was someone on here that was making them to order but I can’t remember who, perhaps someone can point them out for you 🙂
Can someone point me to a decent source for decoding the neck numbers like this ,ie week, day, year, profile etc, I use guitarhq but that seems to just give serial numbers, I’m mainly looking at 68-72 precision’s
