Yes it will, but only 2 of the 3 bumper bar bolts on each side will fit. Use the WB inner guards too so you can keep the overflow bottle and canister where they are. You can use either the WB bonnet or the HZ bonnet, whichever is better. You'll have to much around with the harness a bit to get the lights to hook up. The best way to do it is also to open up the HZ's radiator support opening and unpick the radiator brackets off the WB support, then tack them onto the HZ's support. This way tou get to keep a superior cooling system. Takes a bit of work in unpicking spot welds but worth it in the end. Compare them side by side and you'll see what I mean.
Watch out for WB's with metric threads on the body bolts too and also the inner guard attaching screws ie use the right bolt and screw for the thread.

Na not the gaurds just bumpers and grill and lights...shouldnt have too replace the radiator bracket should i?
