Anyone with a 37 or 38 Chevy running rea parrallel leaf springs with lowering blocks? If so what springs (kit)? And what size lowering blocks (1"/2"/3")? I am using a street rod engineering kit and plan on using 2" lowering blocks, but it looks like I may run into clearence issues with the rear end being too close to the frame. Anyone help me with what they did on theirs? Main object is to get it low but not too low (i.e. bottoming out on any little bump). Thanks.
