Jhaa_lives, a lot of great information in your post!
I must point out that timberdawg's rear cover is not upside down. It is installed correctly. The HO52 under my '67 has never, ever been apart since the truck was new and it is exactly in the same position as timberdawg's.
If the oil filler plug was positioned at the top of the cover, the rear end would be way, way overfilled. Oil would be pouring out the axle tubes regardless of seals.
Again, great post.
