So the LSD went in really easy! I should have taken a picture to show the high quality machining and the mean look of the helical gears.One thing different, and maybe because I am new to LSD's, is that it would turn both sides in opposite directions but was very resistant when turning by hand.
So this thing works really well! There is no binding or odd handling when driving around in parking lots. It locks with no notice of anything but the rear end drifting a bit because both tires are spinning. Very smooth in my 75 behind a LS6 pushing 420 on the dyno, 349 to the rear wheels.
Thanks Exlifesaver! This is a great deal for a very high quality LSD.
