how much more work is involved in putting new gears in the irs. i am getting ready to put 4.10 gears in my 1999 cobra. i have put gears in mustangs before but when i craweled under my cobra and took a look i didnt even know where to start. i bought motive gears and the master install kit. some pointers would be greatly apprieciated.I am mechanically inclined and would like to do my own work.thank you
