I just replaced the u-joints on my 67 Delta in preparation for reinstalling the engine and trans. Since it's an automatic, it has the driveshaft with the rubber isolator between two concentric tubes. The open end of the tube was facing forward, with the trans yoke attached to the inner tube. I didn't think that was right, and a quick glance at the 67 PIM confirms that the driveshaft should be oriented the other way. I assumed this was just an idiot who previously replaced the u-joints... until I found that these were the original factory u-joints still retained by the injection molded plastic rings, so it's been that way for half a century.

DOH!

 

Apparently it won't cause many issues.��

 

And somehow this quality control surprises you? Car built on a Monday or Friday???

 

maybe consider replacing, if water sat in the exposed end it may have rusted the innards and attacked the rubber, better safe than sorry. 50 years is quite an achievement for such a critical part.

 

Which plant Joe? Newbie or sub for the day or bathroom break.

I always replace the rubber with tube in tube driveshafts. I've had too many issues with vibrations and replacement driveshafts are reasonably priced.
