...(AHEM)....the Chevelle wagon has rear coils,not leaf springs(SHAME on you,Jairus) :+) watch for binding of the lower rear control arms on the frame,upper control arms need modified too,I actually sliced mine in half lengthwise,and shortened the mounting bosses. The rear wheel wells allow a lot of lowering,you may need to remove/modify the front inner wheel wells tho. If you go too low,the front cross member drags,as do portions of the exhaust system,especially if you use headers.......Steven Zimmerman aka theZman
