here is one of the threads

someone with a bit of knowledge of the vehicle stated that it's a TJ universal winch mount welded to the unibody upside down, and that the center section of the bumper, while it looks like the factory center of the bumper, actually isn't
apparently the center section is a fabricated aluminum atleast on one of the vehicles, i'm still not 100% convinced the indian rescue kj doesn't still have the entire factory bumper shell
liv42dy is waiting for winter to be over, he's doing something similar to what youre looking for using this mount

part number 60-50059 the 2nd mount on the page pictures
the one you're talkin about that mounts it on the bumper sounds like the detoursbackbone mount
