For what its worth, I modded an 06 grill on my 04. It was a huge PITA. It took me weeks to finish it. I also lost the secondary hood lock latch feature. Its 50 bucks to get the longer 06 one, and I have to figure out how to mount the bracket to the hood. Probably JB weld...I dunno. One day, I might get a color keyed grill and do it all over now that I know what I'm doing. But if it took that much work to change from the 06 to 04. I doubt it would be possible from the tacoma to 4runner.
