I had my '65 posi redone with them and it worked fine.

The whining noise is a separate issue. There are quite a few possibilities if someone was into the diff but generally rear end whine is due to ring and pinion gears or their mating/ relationship/adjustment. Keep in mind the higher the ratio the more likely the gears will whine. I have had many `60`s GM products with 3:42 rear gears and almost all whine a little at highway speeds.

tenugent...I`m not a fan of synthetic oil due to cost and the tendency for it to turn seepage into leakage but for a "chatty" diff this may be the answer as it tends to flow better, especially when cold, and is very slippery/sticky. Please get the band back together,
