Those are not A2 rear shackles, those are Marine rear shackles and expensive if you have to buy a set, I see you have a Marine front bumper, probably had a fording kit in it's past life. Don't worry about the wiring, a new A2 harness is available for around $125, may have to modify if you are still running the in-tank electric fuel pump, if you have an A2 engine then you probably have a 60amp gen, 60amps didn't have a breadbox. It's missing the Marine hub caps, probably swapped out sometime in the past. Hambone
