Funny you should mention 4.10's. I have two sets of 4.10's. I bought them off this board, I think. They are used but I never opened the boxes. I ended up getting a Dana 44 with 4.88's and an Electrac. I later bought front gears to match.
So, I have 4.10's for a Dana 30 and and 8.25 that need to go away as well as the 8.25 axle.
What else do you need?
