89 Lx Grinding Noise On Startup

The most likely cause is a starter that is still running or starter Bendix that is still hung up in the flywheel teeth instead of retracting like it is supposed to do.

Pull the starter off and check the Bendix to see if anything seems to be not moving freely or damaged.

The other possible problem is the starter solenoid sticking or incorrectly wired. I'd post a diagram for you but you didn't give the year model of your car.Therefore, no clue as to which wiring diagram you need. The wiring changed several times between 79 & 95.

That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good Stangnetter and update you sig for future reference & don't keep us guessing.
