I remember trying to get my '57 Chevy up in front in high school. I started cheap with screw in spring spacers. Lifted it up, but with 5-6 in each side it rode like a buckboard! Then I decided I needed ball joint spacers, (which were really cheap in 1966) so I pulled it apart and put them in along with a pair of coils from the junkyard. Raised it up even more, but rode pretty stiff still. I finally broke down and bought a '58 Chevy truck axle and put it in to get the front where I wanted and riding well. I was 17, and the only guy in hi school with a straight axle in his car! Thought I was hot stuff then!
