1981 Corvette Question: AM/FM Radio w/8track Installation HELP!!!!!!

Well, my old Chevys from the Sixties had small support brackets bolted to the back for the heavy radios. Contact Davie's Corvettes in New Port Richey, Fl.

1981 Vette didnt have a OEM bracket that was built for this car. Just trying to find out how it was originally installed. Thanks
