On the stock set up those studs you listed only work on the front rotors. The rears are different, they require a .615 knurl and still require some messing around. I used the MOR-46180 on the rears. But with Ranger axles I couldnt tell you for sure. Take one out and measure a knurl.
The knurl is the "serrated" looking part that actually presses into the axle. As far as messing around, Moroso's qaulity control is poor on those studs so what they call a .615 knurl actually turns into a .625 to .635 so I ended up having to chuck the studs up in a lathe and turn the knurl down about .010-.020" in order to get them to press in.
Yeah, if the stud knurls came the size they advertised they'd work perfect. But when it comes to a press fit a .010"-.020" interference fit is a little to much.
