Need help lowering the rear of a 53 chev

Hey all
I just wanted to know what kind of leaf springs you can put in the rear of a 1953 chev sedan to get a lower ride height than stock? I have some blocks in there at the moment and am soon to do a C notch, but if I can ditch the blocks and mount the diff directly to the leaf whilst still getting about a 4 inch drop from stock I'd be thrilled. I'm in Australia, so anything local and possibly to be found in the wrecking yard would be even better! Thanks kids.

 

see Damo he can help,get them de-arched.

Take the mounts off and move them inside the frame rail and up to the top of the frame. Then move the axle mounts inboard on the axle.
