So who knows maybe its from a 1950s car or a 1990s car. The flex disc, located right next to the differential on the driveshaft, appears to be in excellent condition and there is no evidence of looseness or play in the driveshaft itself. I felt it when it was on the lift. Firm.

I just bought the ebay one. I really hope I don't have to rebuild the driveline. Rebuilt driveshaft for my old bimmer with core return was like 500 bucks in parts alone.
