Ford 8.8 RearDifferentialCoverBolts, 10ea, 13mmHexHead (1/2" Socket if rusty\worn). Soak with PenetrantOil for ~hour before trying.
Don't have here the ThreadDiameter or ThreadPitch or ThreadLength.
Be sure you can loosen the FillPlug before you open the cover or drain the Diff; if FillPlug is stubborn, don't want to drain Diff until you solve that first.
Can remove TopCenter Cover Bolt & take that to your local hardware or order online & get equivalent FlangeBolts;
this is just a cover bolt, not a structural bolt, so does not need to be Grade8, Grade5 should be plenty strong.
Torque is 33fp, again just a cover bolt, so don't over tighten.
Use a dab of AntiSieze\AxleGrease\Vaseline\GearOil on the threads;
a courtesy for next poor bas'ard who works on this vehicle+part.
