My 67 Camaro mono leaf shackles are faceing towards the front, and the spring is against the frame. I just bought the car and tried to replace the shocks and discovered that the shocks were in at full extention and were locked up. New shocks will not reach down to the bottom bracket. If I remove the shackle bolts can I get the shackles to head towards the back as they should? The springs are a correct Moog mono spring.
