Check out this baby. 1970 e-bay Dart.

Ummm no. It's a '70.

My bad, I should have said '72/up, sorry! I also should have been more clear, it's a '72/up Scamp bumper.

1970 and '71 jacks grabbed the bumper from underneath:


'72/up jacks had a hook which fit into a slot cut into the bumper under the taillamps (much worse design, IMO)


Hence, the bumper on that car was replaced and is not original. What's more, if you get a flat rear tire you're screwed, because you don't have the correct jack for that bumper!
