For those that have the plastic bumper, you can use the Mopar rivnut part #6511076AA to secure the winch plate bracket inside the non threaded holes. No special tool required. (You need 4 rivnuts ).
I just read a review on the EVO website that the No Limits manual knob works on the JL. Can I still do the motor flip with this bumper set up, or will the winch plate interfere with the manual disconnect?
