If you go on any auto parts website and look for a part, take note of the part#/parts#'s. Then look up the part as if you were purchasing it for the donor vehicle....match? Already did it for you and part#'s didn't match. That's my process. There are probably better ones.
I know sites like summit racing, with more specialty or custom parts, will give u a cross reference type list for certain parts. I think that is pretty cool, but unfortunately they aren't in the Toyota replacement parts business, lol.
There used to be a interchange manual by Hollander (?) that gave all that info. Not sure if they still publish, but many salvage yards may have old copies around.
