The Yahoo Previa group's files will be deleted on 12/14/19. Over the years, I've saved a lot of them that might be useful to my '92, and just went back to download some stuff I only had saved the links to.
I suppose there's a way to copy everything over, but there's a lot of stuff that isn't relevant any more, things like for-sale listings. The rest is a mixed-bag as all these things tend to be. I'm sure many, many of the original posters are long gone along with their vans and preferences for sites less clunky than the Yahoo one was.
Now, I don't have the time to search throughout this site to see what may or may not be duplicated, nor what other Yahooligans are currently registered or may have arrived recently. As an intermediate measure, I copy-n-pasted the file list into a pdf - which preserves the links if you can still log in there - and am willing to copy any of them over on request (although no guarantees as to how promptly).
FWIW I also have accumulated notes on different topics which tend to be a mashup of c&p'ed comments made on different threads, sometimes pretty inconsistent when taken all together, but info is info, even if it has to be filtered/vetted later. Those are available too if you have a topic, but don't expect anything polished. There's often an agglomeration of inputs from Yahoo, this site, Toyotanation, something a parts guy maybe told me, plus some random blog or three...
Don't worry, nothing from Scotty Kilmer
So, if you know there's a topic that needs some extra Previa info here and you see it, let me know. I either have it myself or can go get it.
