I did the upgrade on the tail-lights on my tub - just needed the upgraded harness for the rear tail-lights as ONE plug is different. Otherwise, Plug-N-Play
Everything is interchangeable I believe - I had two Hiluxes next to one another and the mounts where in the same position on both
I am sourcing:
-Bonnet
-Front Guards
-Grill (Aftermarket)
-Headlights (Aftermarket)
As for the roll bar in the tub - I am not 100% sure the drill mounts are the same.
