Re: Lead for a BE Rear
Posi springs appear to be the correct natural color and not Green color as are the standard posi springs. I think casting #30174 was a 4 series posi carrier casting # and don't know if the BE rear used a different casting. Spider gears should also be slightly larger than the standard posi. Seller should supply the ring gear P/N if possible to verify the special heat treated 4.10 gear. Axle tube stamping looks good.
