I have a couple of digital manuals. Let me see if I can pull those numbers though. The only thing I've had problems with is the front TT gear set it is very easy to order the wrong tooth count. Is your 500 modified or is it a PRO?

AGNH50G002XX Align Torque Tube Rear Drive Gear Set
AGNH50095A Align 500 Torque Tube
[AGNH50G003XX] Align 500 Front Gear Set (31T) This is the one that fits mine.
AGNH50082B Align 500PRO Metal Tail Pitch Assembly
AGNH50119A Align 500PRO Metal Tail Rotor Holder
This one doesn't work on mine... I don't have a 500 PRO AGNH50G001XX Align 500PRO M0.6 Torque Tube Front Drive Gear Set (36T)
Count the teeth on yours, if you need the 36T I have 2 sets of them you can have. I ordered them by mistake, twice.
