The center bolt of the spring pack (on both front and rear springs) is not in the middle of the spring, so if you put one long end forward and the other rearward, it would make the axle cockeyed relative to the frame (not perpendicular.) But it would be pretty obvious. The bushings are different front and rear too, so you could only do that if you pressed in the bushings yourself. Not an issue with new springs with bushings already installed, but it is possible the supplier put them in wrong.
[on edit] I don't recall which way the short end goes (front or back). I'd have to go out and measure on my chassis.
