Funny you ask as they've let me in with my 87 T since I got it six years ago and the "cut-off" year was even prior 85. If you're entering the car show, that might be an issue but, if you are only scoopin; no problem at all. Should they ask, which they won't, just say it's an 85... they won't know.
Usually a big turn out with many beer tents!
