I have a question about the early and late 4 speed differentials. I have two 74 Mark 2 cars. Both have the larger driveline flange on the differential. My 2nd car is John Kimborough's damaged car, and the rear differential housing is bent. I want to replace the diff so it will roll and drive. I know where there are several 73 mark 1 parts cars in the area but I'm sure they have the smaller diff flange. Can the flange be interchanged between the two? I know about the crush pinion sleeve, and that doing this swap might, or wouuld require the gear mesh to be re-adjusted. Is this possible for a reasonably talented home mechanic? Or should I just look for a later 4 speed diff? I know I could just swap the drive line as well, but I would rather keep the later one with the larger U joints. Anyone know where I might find one in Oregon, Washington area? Gary
