Want to lower my 66 Dart

I lowered mine with two inch blocks in the rear and turned down the torsion bars in the front. The local parts stores sell the blocks with bolts in kits but I never found a kit with the correct u bolts. The early A cars have smaller sized rear end housings that use 7/16 u bolts instead of 1/2. So I had to go to a truck shop to have new u bolts made up in the correct size. I went with 2 inch blocks thinking it would just lower it a lil but my original leaf springs must be sagging because its pretty low. By the time I had the front almost level with the rear there wasnt much clearance left for the bump stops.
