the pinch bolt brackets in position one side, won't tighten them up until the other side is in.
I do like a project, but mine is definitley for driving though. She was my daily for many years before 'The Big Rebuild' and none of the replacements (more like stand-ins) have ever been the same 🙄Take your time RFG, remember, we do this, not because we need a car, we do it cos we like a project, what's not to like about a Tinker?
Don't be too hard on yourself... I once replaced an entire gearbox/axle/rear drum assembly, only to find out the reason the car no longer moved was because the splines had worn away in one of the drums 🤡Here's a fine example of how not to overthink an issue, always try to consider the least path of resistance. So my Moggy Pickup, two rear wheel bolts won't tighten, so off it all came, the drum, shoes, snail adjuster. Lucky that the new stud goes in without having to pull the hub, just enough room between it and the brake backing plate, out came the marked pair of studs, in went two new one's.

in they went using a nut to squeeze the splines into the hub. The old one doesn't look too badly damaged,
not enough to cross thread it. Low and behold, it's the wheel lug nuts that are faulty, would have been such a easy fix.

Or it could be on the fan collar, it's a veeeery long time since I removed my alternator from the shroud. On the last rebuild I just lifted it all as one piece.The only way to tell if the fan grates when on the engine is to bolt everything in place (fan shroud, dynamo strap) and then spin it. It can catch if the shroud is just slightly out of place, but you won't know until it is fitted properly.
If it is still catching then shims need to be added on the shaft between the dynamo and the fan collar.
