Whoopsie - LOL!

I didn't say anything when I first saw the pic as I figured you wouldn't have stood it up for painting full of earl. Many of the earlier manual transmissions didn't use seals at all, just a "slinger" to keep oil back out of the input shaft collar, and those only work when on a mostly level plane and oil level is at proper level or below. Sometimes parking on a steep downhill slope could result in oil getting out and ruining a perfectly good clutch.
