Interchangeable bumpers???

I have a '91 grand prix se that needs a new bumper. I have found a '94 bumper for sale that looks the exact same. Is it?? Will it fit the same? Any help appreciated. Thanks!!

you may have to grind off the two locating pins near the reinforcment to make it fit your 91, but otherwise, as long as the bumper covers look the same and both cars are the same trim level.(there are different front facias for the GT, GTP, SE and LE models)
