I have have watched videos showing that the lower shock mount where the U-bolts go through comes off after being unbolted. Mine seems to be part of the frame. My rear shocks have an eyelet on the bottom of the shocks, and the bolt for the shock is part of the the place that is part of the frame. My question is, since the new leaf springs are 3 layers thick (3 springs together) instead of a single layer. What is the best way to make room between the shock mounting plate and the axle. Do I need to remove the U-bolts and the shocks from both sides of the car and raise the rear end with a jack? Besides the cart being supported by jack stands, is there anywhere else that needs to be supported to safely do this? Will raising the axle with a floor jack to get the new leaf springs installed cause a problem with the drive belt? Will I also need to purchase shock extenders? Thanks in advance for your help!
