the rear rubber bumper bolts straight on with the same brackets-only the fronts had unique brackets. good luck in finding a great original and what i`ve heard of the repro ones are not 100% like the factory ones.
i do like the look of rubber bumpers and they are a bolt on item so it doesn`t mess with things if you want it looking like the tag.
it also looks good with the chrome...
all the best
