A body drive shaft and yoke
I live in Corpus Christi. I have a drive shaft that was inside (in the passenger compartment) of a 67/68 Barracuda. I have no idea what it fits but I'm pretty sure it's Mopar. I can get the length and the yoke diameter/length if you're interested. I'll sell it for $75 plus shipping (unless you can pick up). It still has the yoke attached.
