I just got my lift for my 72'. I got the Tuff Country 2" suspension. The rear springs only measure 49" from center of eye to center of eye. Is this right? The ones on the rig now are 52". Will these settle out to be the correct length or are they the wrong springs. The front ones are about the same length. I am waiting on a response from Suspension Connection where I got them but I figure I would have better luck here. Thanks
