Here's a document from the time, which exposed 1975 as it was unfolding.
I've also attached a document which is an unstructured collection of 1975 observations, reasoning on the WT teachings and comments, and looking at how they republished certain books with changes to hide their 1975 teachings etc.
If anyone fancies sorting through these they might find a new angle not previously considered.
However the bottom line is that there is a ton of evidence that WT were pedaling 1975 to the masses for years.
How they try to turn around today to pretend otherwise is nothing short of hypocritical cowardice.
