You should be able to get the records from the court. It may be tricky, as HYTA cases should be kept under seal and your name mae be suppressed in their computer system.
Without knowing the full facts of the offense, it's hard to say how much of an impact it will have. But 17 years ago, unless you were in a County which followed unorthodox practice (such as Washtenaw), HTYA didn't even require a guilty plea. (Now you plead guilty, but if you successfully complete probation a conviction is not entered. Back then if you violated your probation they went back to the plea stage, and you could still take the case to trial.)Quoting MICHguy
