they look identical, don't they?
firstly, it's not the bumper that you dented, but bumper cover, or fascia.
secondly, they may look the same. BUT. there's always that infamous but. you never know what is inside of TCH's bumper cover. it's different powertrain; have little doubt, there's a lot of extra parts that run inside TCH's cover vs. SE's one. and that where you start taking chances.
i'd say, find part numbers for bumper cover for both models. if they are identical, you might get lucky. if they are different - DON'T! it may end up in messing up HSD, and that is a costly thing to do.
