Hello Flatfender Fans: I finally got around to having a lockrite locker installed in my 3A rear diff. I am not satisfied with the clunk clunk noise it makes especially in left-hand turns. Exploring other possibilities, could an air or electric locker be installed in a Dana 44? A 3A is supposed to have a 44 rear, right? Not a 41? Or did Willys interchange those rearends in '49?
