do seat backs lock if so how do they operate mine will not move at times and move at other times also hot to you adj seat back
Sweet ride you have there.
I’m not certain the year they started locking seatbacks, but most were simply clipped in when pushed rearward.
Unless the corvette was equipped with an option such as power seats then, I would say either the seatbacks were not adjustable or used a leaver.
I’m sure someone familiar with 'vettes will guide you correctly.
Perhaps you could get a good answer on a site devoted to classic 'Vettes.
