70-71 Dart Jack hook

Check the bottom edge of your rear bumper. Good chance it still has the notches for the hook. I know a 73 Scamp rear bumper I have has both the slots for the 72 up style jack as well as the notches for the 70 hook.

the only thing is, I have a 72 jack already. So even if my rear bumper has provisions for the hook, I’d need a different jack and the hook
