Security clearance with very old Juvenile record in1979

Looking for one last job before I retire and have a very old Juvenile record, and some of the jobs require a security clearance. Problem is, I was arrested as a kid, under 18, for breaking into a garage used for storage and burning down a shed. Two separate occasions. I don’t remember the details of either one as far as specific charges went. Each incident carried more than one charge, and each one was pleaded down to a lesser charge. Problem is, I don’t remember exactly what the final charges were. Maybe one of them was criminal mischief and the other something similar. I don’t even remember if the final charges were misdemeanors or felonies? I’m not sure where I could even get that information at?

Any help would be appreciated!

You can pull your own record with the court and get all that information.
