I have no idea on that...this is tough enough just doing this swap...I would just bust em open and look at each one side by side and do a tooth count on each one...on mine they have 2 sets of gears that have a different count on em, different by only 1 tooth, but swapping the entire guts is the only way to insure that they are set up and mesh correctly...
I am making a press so I can complete my swap, must have 2 and 3 finger pullers, with long grabbers, as well as a press, snap ring plires and more....hope to have it done in a week or so....time is my issue.....very limited... :sob: :sob:
