Obviously!
My point here is to be careful if attempting to straighten an Avanti (steel) bumper off the car, as it’s quite easy to damage (crack) the chrome plate….
Also, if the Avanti in question is going to be driven more than occasionally, as I do mine, I believe that a bit of extra clearance over factory spec between the bumper and the fiberglass body is a prudent move.
After repairing more Corvette and Avanti fiberglass bodies over the years than I care to remember, that’s my take on this.
