I'm sure this has been done on 782Ds and 882s etc. I have been told that the fuel tank will hit the top of the transaxle where the 4 bolt plate is. How did you who have done it, get around that? I could probably mill that area down and use flat head screws on the plate. I want the extra weight of the CI case and I'll put the fine spline axles and 2 pc carrier in.
