I need to replace my stock 2.73 rear gear with a 4.10 and would like the part numbers of the options that will fit along with an install kit that includes everything I will need. I know 100% my current gear is a 2.73 as i pulled cover and checked part number. I assume it is a series 2 carrier so I will need a 4.10 for a series 2 carrier + install kit that includes everything I will need please. Richmond or Motive? Thanks!
