I have a big block 1969 Camaro that I have changed over to a small block. It rides hard and I would like to change it to ride softer. I was wondering if I changed out the front coil springs and the rear leaf springs by going with stock small block replacement springs will there be any match up problems in bolting them into place? Are the rear spring perches in the correct position to change over from a five leaf spring to a four leaf spring set up? Also what will happen when I change over the front coil springs to the ride of the car? Do I need to change over the front coil springs or are they the same as a small block car? Thanks for the help Mike
