3.91 or 4.10 8 3/4 Third Member

I am looking for a good set of gears for my Demon. Prefer 4:10, but a 3.91 at the right price would work. Located in Maryland and can pick up if near by or willing to pay shipping cost.

Thanks!
I work in Sterling VA and have 3.91 gear 741 case with a ratchet locker up for sale. We could meet close by. Let me know.
