Rear End Swap 7-1/4" to 8-1/4"
Here, the new rear is waiting to be suspended by the SS springs. I simply dragged the rear underneath the car then lifted each end with a jack and supported it on jackstands. I used a jack to hold the nose up. Once the springs were in place I moved the rear end into alignment with everything and then lowered it onto the springs. It's not as scary moving it around when the springs are underneath it because it does not have far to fall. I also allowed the pinion to point down to floor which makes it easy to eyeball if the spring perches are lined up with the front spring hanger mounting locations on the frame of the car. I was within an 1/8" when it came time to clamp everything together. Take a look at the front spring hangar, this is the part people talk about flipping upside down to lower the car. This requires elongating some holes as the stud width is different from top to bottom of hangar so it would only mount in one way at the factory when it was new. Mopar performance sells new hangars with an extra leaf spring bolt hole so you can lower the car without modifying the attaching points on the frame. They are about $65.00/pair. Elongating holes is free though:)
