" " If you care about handling, the amc15 axle is about 100 lbs " lighter than the amc20. That's a lot of unspring weight, in the " rear of a car with a light rear end to begin with. I don't think " there's a twin-grip amc15 (others may have facts), but they're " cheap and plentiful. yes, there were twin-grips. also, dana 35 posis, of which there are a plethora, fit, since it derived from the amc15. i think there's even a tru-trak, which would be my choice. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought
