Rear leaf springs, new or rebuild old ones?

[69Z28-RS]

Yes, one clamp holding 2 leafs and the other end holding 3. In thinking about this, the holes in the short leafs are 1-1/2" off-center (the leafs are the same length as each other). If one leaf is opposite and the spring packs laid side-by-side, as mine are, then you see a difference of 3". The wear marks in the adjacent leaf (the ones above) shows a distinct wear pattern, there's no mistaking the original location. Now I'm just wondering if the significance is so small, the assembly line workers may not have cared or been able to tell if they flipped one during the build

Dale, I *think* you are saying that there is 1.5" longer portion of the spring to the rear of the 'hole' than to the front??  which means the hole is drilled 3/4" off center, so yes, if it's rotated 180 deg, then the position of each end will change by 1.5"... ?   correct?   I think on my spring the rearward portion of the small leaf might be 3/4" longer than the front (just from 'observing'), I don't want to take it out and measure it.  I'm potentially thinking that someone rotated that leaf on one of your springs, possibly thinking that it might help them get more even force for the two tires in an acceleration contest?     Mine have not been apart, and I suspect that will be the consensus as more people report.  I've never read anything about the springs being assembled differently from the factory.

Check for inter granular rust. My 70Z springs were almost fused.

Are you in the rustbelt, Buddy???

You're right, Gary. My bad. The holes are off center 3/4". We've rotated the spring to make them alike, with the slightly longer ends towards the front of the car.
