Open diff w/4:10 ?

I dont think you will have roasting tire problems... But right now I know that if it is even a little wet, and I am on a hill at a stop, Its a pita to get going. If I had 4.10's and no locker, I probably could not make it to work. There is a low water crossing that I have to drive through. And a steep hill after it. I have trouble going up it with stock gears.
If it was me and I knew I would not be able to get a locker for a while, I would have gotton a locker first. It would have been very easy if you got something like power trax because it takes the place of the spider gears. Install is easy with no gear resets. If you want to put the 4.10's in at least find a stock govloc for cheap to throw in. They can be like $50 sometimes.
Just My 2 cents.

I was going to make the same suggestions as jeff, no more power then you are putting down I would look into a govloc as a temporary fix.
