Changed the front to coil overs and just did the back conversion to make it a matched pair. Easy to follow directions and with two new holes drilled per side an almost bolt in installation. These make the difference in the stance of the car!

Do the factory coil springs need to be removed for the shocks to be used? Is the 150lb rated shock good for a big block car? Thank you, Joe
