I believe they are different... I think the valence has to come down lower @ the top for the 76+ style grille... the prior grille doesn't dip @ the bottom like the 76+ Check out the pic in this thread: http://www.toyotaminis.com/forum/showthread.php?p=59309#post59309 You can see how the grill is a little off, but it kind of highlights the bottom of the older style grille on what appears to me as sitting above the 76+ valence
Interesting question. I'll go out and eye-ball the one on my 77' and 72' and see if there is any difference. I think I have a tape measure somewhere...
Definitely different. Valance on my 72' is definitely different than the one on my 77'. There wasn't even a need to use the tape measure, you can eye-ball it and see the difference.
