Looking at the pic, there isn't a premade bumper that is going to bolt onto the front of your truck, you are going to have to either have to fanricate a one-off bumper, or modify an aftermarket one. Since 3rd gen trucks bumpers mount from the side rather the the front, it would likely be easiest to fabricate some side mounts that you would weld to the side of the new crosss member, then modify an aftermarket 3rd tube winch bumper to fit around the winch.

IIRC, there is about 36-37" between the 3rd gen mounts.
