Don't waste your time and money. The '93 bumpers are/were the same as the bumpers on my '88, and although they are metal I would say that using the word "strong" in the same sentence with "'93 bumper" would be an exercise in self-delusion. I've replaced the rear bumper on mine twice, once for rust and once for a very minor hit. I also have a couple of parts heaps with twisted front bumpres that pretty obviously were not hit very hard, but twisted the bumper like a pretzel.
Save your pennies for a real bumper.
