Suspension Help

[Scarface]

Thanks guys I am going to try and get this centered up this weekend. I am looking at lowering my car 2 inches in the back and I can't seem to find to many people making a 2 inch spring for the back of a chevelle. So I am thinking about the QA1 coil overs I just have a question about them. Do they install where the shocks are and if so do you just remove your coil springs completely or do you have to do some fab work to install them? (Same question for the front as well)



Thanks
