Can anyone tell me how fit these rings to get them centered and the scope perfectly straight and inline with the barrel? I can't find anything online about them.

Just do by eye if one side is closer back off that side and screw in the other side try to keep them even, or count the turns in as you tighten
They look like they are designed to fit the parker hale style bases.
Got a pair just like them that was fitted to a gevarm i had
I'm guessing you are fitting them to a 303 that has an old rail fitted. Just screw both sides fully in and back them both out equally repeat in reverse when tightening them up. As carbine has said. Or you could fit them to an aligning rod or a scope and use that to align them. They are great rings to use if a rail or bases aren't aligned correctly.
I think they are called Zero rings (Brand name Zero not a reference to a type)
Most of the time you will need a lapping bar to make sure they do not twist the scope. In all honesty, they were never expensive rings and probably better off being replaced. In saying that, I used some to mount a spotlight on a scope many years ago when cables and halogen was a thing..... Removed the bolt from one side, replaced it with a bolt that was about 1" too long that had a wing nut fitted before attaching it to the ring. That way I could tighten or loosen it by hand and the wing nut was captive so it did not get lost in the field....
Simplest way is to clearly mark the centre of the ring, and mark the centre of the base you are attaching it to. Then make sure those marks line up and put it on the rifle without the scope. Then use the lapping bar (or any on inch tube to push through the first ring and make sure it lines up with the other ring. Height should be sweet, but you may need to move a ring left or right to let the bar line up. Ones lined up tighten them carefully and check they have not moved using the bar to make sure they still line up. Once that is done, at that point you can fit the scope. But I would bever use an expensive scope in these type of rings, if something works loose and is not tightened correctly it can easily twist or damage the scope. As mentioned, the best solution is not to use those.

The OP's are very similar to rings that Millet make.
Now having critisised them I have a set of Millet rings of that type on a service rifle with side mount. The Millets let me zero at 100yds without adjusting the scope windage to the extreme.
The Millet rings side clamps are designed to skew to accomodate any offset. Whether the OP's will do that I don't know.
Lapping them if they are radically offset is a waste of time, would take forever. Too much metal to remove.
I wouldn't use those rings unless I really needed the extra windage adjustment. A Norinco .223 in my rack has scope bases on the piss and I think those Millet-style rings would work all right.
