As said need tyre size, can't figure it without, but simple to do with diff/box tyre numbers.

I'm not sure what the 5th gear ratio is on the box you have, pm me this and I'll work it out and pm you back, but I've put up the formula before on pf/gd so a search should find it.

5th gear in a std 4x4 box is 0.83
so filling in the boxes on the link
speed at 6700 is 150.2mph
