On my 70 Challenger the rear shackles are about at the 1 and 11 oclock position. Is this acceptable? I think I saw somewhere that 2 and 10 oclock positions were preferred. Also with my ss springs should I be running a pinion snubber? I do have the mp longer shocks. What adding other clamps?

Should be about 35* to 45*... if your SS springs are
any good you dont need a snubber,,, the car should lift
with out one... the bottom of the shackle should be
to the rear... clamp all front segments... and decent
adjustable shocks at all 4 corners... minimum 9 way
Ranchos on the rear and maybe the Caltrac fronts

E-body's are a tough fit....I went with adjustble shackles and cut the lowest position off because it wold hit the valance...
