got a set of 4.10 gears that i believe are made by Motive. the ring has a Ford logo on it as well. they were installed in my car when i bought it a few years ago and swapped them out for 3.73's when i built my rear end. nothing wrong with them, never made any noise. looking to get $110 for them.
heres a couple pics with the model number on them:
