Which grill should I use?

[v8skantkeepup]

I am putting together an 84 Regal Limited. I have my choice of two grills...One is from an 85'(with the chrome strip that reads "BUICK" accross the top), and the other is from an 87'(just verticle ribs).
I am having a hard time deciding which one to use...
HELP!!!
85' or 87'?????????????????????????????????????????
