So if you hit the side of the bumper, you would need a full after market bumper, as opposed to a middle cut out. My understanding is that most off road/ after market bumpers are going to bolt up to the frame/ you would take off the crash bar and wouldnt use the bumper cover support and bracket.

Otherwise - look on facebook marketplace/ local 4runner groups for people parting out their cars or upgrading their bumpers. Depends what your budget is. I mean itll likely be around $200 for the new bumper cover and parts maybe another 100-200 to paint it. An off road one will be around 1000, but if you have the budget/ and or will use it
