If you divide 43 by 13 you get 3.31 so that is the ratio.

That should be fine for a Rover engine. I have a 3.54 in my Chevy powered car and you get great acceleration but a bit less top end speed.

If you can turn each wheel independently of each other then it is a standard open type diff or it's a completely knackered power lock one!
