Also, the pins should be clearly marked so one can easily identify them. There seems to be at least one instance of an incorrect pin being installed which was caught on ground run up. Or redesign so all three are the same.

And, maybe an inspection procedure should be developed using a camera/bore scope so the engine does not have to be removed to inspect.
Inspection of the Rod end hardware should be covered on installation by a duplicate inspection.
Post installation hardware can be checked for installation with a boroscope from the gearbox end going in through the Suspension bar hole in the rear firewall.
Torque checking of the suspension bar airframe fittings hardware will require MRH fairing /Engine/interior trim removal.
