Welcome Visitor! Please take a few seconds and 
i have a 2005 ranger xlt with a ford 8.8 and an open diff with 4.10 gears(axle code 97). i want to put in a limited slip or some sort auto locker but i dont know how many splines are on the axles. anyone know? im also looking for some suggestions on lockers that will hold up but still be civil on road. it also has a 4.0l if that makes a difference. thanks
