I am in the process of replacing the springs on my 69. I was having problems getting both sides to align centered in the wheel well so I removed all parts a second time. I then installed all parts except the rubber pads to see if everything would align properly, and it did. However, I noticed when the car was sitting on all fours, there was a 1/4 inch to 1/2 inch gap between the bottom of the spring and the perch. Is this normal? Do the pads actually take up that much space?
