i thought they may be to small as this is a 1985 ute with the big diffs,
but thats good news wich of those 2 is the lower ratio?

higher the number lower the ratio. Alot of ppl say that its such a small difference that it is ok and others say that it will wind up the transfer case. I havent seen it first hand so i dont know who to believe.
If you have a HJ or FJ which is what it will be being an 85 it will still fit they are the same size. It will also fit in the front if you wanted to.

Correct
Its not too important but its the other way around
4.11 (37 x 9) for ute/troopy and 4.1 (41 x 10) for 80 ser

The difference in ratio is about 0.2%. This is much lower than the difference if you had new tyres on the rear and half worn tyres on the front.
On a part time 4wd you won't have a problem as you are unlikely to be in 4wd on high traction surfaces like bitumen anyway. I have had a 70 series rear (has an ARB locker in it) in my part time 4wd 80 series for nearly a year and not a problem.
