It will be fine i was just a little grumpy. As i said it won't work like a SS Spring, or as well, but it will be much better than a aged stock leaf spring!!!!
Same story with the HD spring, but it sound like you already own the SS Springs........
Look on the bright side, you will only need to buy one spring if you can't get it to hook.(unless you making lots of HP, slicks will keep you in a straight line):)
