I recently started doing the spring over in my 93 YJ, I have 5.5 inch springs and am doing the shackle reversal, the rear end perches matched up perfectly, but the front doesnt look like im going to be so lucky. Does anybody know what the difference is in the perch width between a ford dana 60 ans the stock 30? Any help would be great
