I ordered two spring sets of 1750lb rating each, 4 leafs total per spring. However, on the old one at the slipper end, it has two leafs, as oppose to the new one having only one leaf. Is it okay to use the new one? On the trailer, the slipper end touches the frame, and a long screw right below to secure it from falling out. I think the rating are the same base on my 18.5 Mckee CC Pulse boat. Thanks.
