Hello! I'd like to know if anyone out there knows the correct length of the leaf springs for my RV. I really don't want to remove one to measure it the way they show you to do on different websites. I did measure it from eye to eye on the trailer and I get 25 3/4". The closest one I can find to order is 25 1/4". Is this the one I need? Is the extra 1/2" because it's stretched a little because it's on the vehicle? Any help would be appreciated!! Thanks, guys!
