Hi I have tried to fit the 3.08 into my rear axle and when I put back the pinion gear seems to big as it causes the planet gear casing to stick out making it impossible to put back slide in my half shafts any ideas, also bought a 3.42 crown and pinion and thats the same can you get a thinner planner case or could I get another axle but I don't want to lose my 6 stud
