SS or XHD springs for 66 Dart?HELP!

ya could have taken the old set to a spring shop, have them add another main leaf (will only add about 1 inch in ride height) and then have them add extra clamps to the front segment on keep one on the back (some cars like more clamps some less, but i went with 3 on the front of mine and 1 on the back to start with)...all that for 100 bucks, and they should work as well if not better than the xhd's...just another option if ya need it for next time
