i didnt use it. the shaft had enough play I could just slide it out

 

just watch your heater core lines at the firewall... the instructions dont mention it, but my plastic connectors were old and dry rotted, so when i started lifting, the outlet hose snapped. cheap fix, but annoying.

 

I have also heard that if you use the bumper relocatin brackets you can't tow using a reciever hitch on the bumber because the brackets they give you aren't strong enough.
